Project leader: Dr. rer. nat. Hulman Martin
Annotation:The discovery of graphene in 2004 has brought a massive interest of scientists active in condensed-matter physics on research of 2D materials. Even though these materials have a long history starting already in the twenties of the 20th century, the past years have seen an intensive renascence of interest in 2D materials. Ultra-thin samples of many 2D materials have been successfully prepared with electronic properties that may exhibit correlated electronic phenomena such as charge density waves and superconductivity. One of the well-studied families of the 2D materials are transition metal dichalcogenides (TMDs). TMDs consist of hexagonal layers of metal atoms sandwiched between two layers of chalcogen atoms with a MX2 stoichiometry. In this project, we focus on those materials from the TMD family that exhibit strongly correlated electronic states: NbSe2, TiSe2, TaS2, TaSe2 and PtSe2. The goal of the project is to prepare ultrathin (≤ 10 nm) layers and bulk samples and characterise them thoroughly in terms of the thickness, crystallinity, homogeneity, optical and electronic properties. A special attention will be paid to charge density wave states and superconductivity in these materials and how they evolve with the sample thickness, doping, external electric and magnetic fields and details of the growth process. The scientific program also aims at preparing heterostructures built up of these materials as well as hybrid systems combining TMDs with other materials. This research also includes a detailed characterisation of heterostructures to provide a feedback to optimise the growth process.

As part of the project, we will investigate the possibility of superconducting behavior of a two-dimensional MoS2 system deposited by pulsed laser deposition.

Low-loss superconducting CORC-like cable from REBCO conductors

Duration: 1. 1. 2021 - 31. 12. 2023
Program: VEGA
Project leader: Mgr. Seiler Eugen PhD
Annotation:Aim of the project is to elaborate the design of a superconducting CORC-like cable with considerably reduced AC losses. Project is focused on identification of the key parameters of the cable design, on the construction of model cables and their experimental characterisation. The research will follow two basic directions: optimisation of geometrical layout of the individual REBCO tapes in the cable and investigation of possible utilisation of low conductivity materials for the central core of the cable. Geometrical optimisation of the cable will be based on results of numerical simulations employing the Finite Element Method and the Minimum Electro-Magnetic Entropy Production method. In the experimental part, sets of short model cables will be manufactured for tests of different geometrical configurations and different materials for the central core. Investigated will be the total AC losses, basic transport parameters and degradation of superconducting tapes due to mechanical loading in the cabling process.

TREND - Optimization of round high-temperature supercnoducting cable for pulse magnetic field

Optimalizácia okrúhleho kábla z vysokoteplotného supravodiča pre pulzné magnetické polia

Duration: 1. 7. 2021 - 30. 6. 2025
Program: APVV
Project leader: doc. Ing. Gömöry Fedor DrSc.
Annotation:The project is focused on an optimization of a cable made of high temperature superconducting tapes wound on a core in form of a tube with the possibility of cooling the cable by the coolant flowing through the former. The purpose of the optimization is a significant decrease of AC losses, which can be achieved through three modifications of the cable. The first one is to reduce the width of the 4 mm superconducting tape down to 1 mm with steps smaller than 0.2 mm. The tuning of the tape width should allow to prepare the cables with optimal packing of the cable layers and with greater flexibility. The second modification is an additional narrowing of the superconductor width by striation scribing the superconducting layer along the tape with already optimized width. Both processes require a development of a suitable method for the cutting and scribing process of the superconducting tapes with minimal impact on their mechanical, structural and electrical properties. The third modification is the innovation of the central former, which should fulfill requirement of significantly reduced electrical conductivity. Modified superconducting tapes and cables prepared from them will be characterized in terms of mechanical and electromagnetic properties. Most of the experiments will be supported by computer modeling.

Duration: 1. 1. 2021 - 31. 12. 2024
Program: VEGA
Project leader: Mgr. Sojková Michaela PhD.
Annotation:Thanks to the unusual physical properties, 2D materials have been intensively studied for several years. An interesting group of this class of materials is transition metal dichalcogenides TMD. They have a hexagonal structure with the individual layers bonded to each other only by weak Van der Waals bonds. This causes significantly anisotropic properties and has a significant effect on their electronic structure. Some of them show physically interesting correlated states (superconductivity, charge density waves). The primary goal of this project is to prepare and study the properties of thin layers of 2 different TMD - MoS2 and PtSe2, and to study the influence of doping with Li and Na cations on the electrical and structural properties of these layers. The secondary goal is to optimize growth and doping conditions to improve the parameters of thin films, such as electrical conductivity and charge carrier mobility which will enable the preparation of functional electronic components - transistors.

Program: APVV
Project leader: Dr. Mruczkiewicz Michal
Annotation:In this project we will focus on the theoretical and experimental investigation of spin wave dynamics at nanoscale. Spin wave is considered as candidate for an information carrier in ultrafast and energy efficient information processing devices. It is due the unique properties of spin waves, namely low heat dissipation, possible manipulation at nanoscale or reconfigurability. We are going to investigate specific spin wave systems, that can host robust, unidirectional and reprogrammable spin waves. Therefore, the results of this project will contribute to the field of modern magnetism, magnonics.

Thermal stabilization of high-temperature superconducting tapes for fault current limiters

Duration: 1. 1. 2021 - 31. 12. 2024
Program: VEGA
Project leader: doc. Ing. Gömöry Fedor DrSc.
Annotation:Additional thermal stabilization is necessary for commercially available high-temperature superconducting tapes, in order to use the tapes in devices for fault current limiting in high-voltage grids. The proposed project is aimed at fabrication of thermally stabilizing composite coating (epoxy resin with ceramic filler), which will act as a sink and absorber of the heat produced in a limiting event. Various materials for thermal stabilization will be tested, with regard to their thermal, physical, and mechanical properties, and their resistance against thermal shocks. Possibilities for improvement of mechanical properties will be investigated by additional reinforcement of the thermal stabilization. The effectivity of the thermal stabilization will be determined for superconducting tapes from various producers, by experimental limiting of fault current. Experiments will be complemented with numerical modelling.

Vertical GaN MOSFET for power switching applications

Vertikálny GaN MOSFET pre výkonové spínacie aplikácie

Duration: 1. 7. 2019 - 30. 6. 2022
Program: APVV
Project leader: Ing. Kuzmík Ján DrSc.
Annotation:Owing the ever growing demand for the energy volume, energy attainability represents one of the most important issues of today’s society. However, there are great reserves in the energy savings available. According to available analyses, more than 10% of all electricity is ultimately lost in the form of conversion losses. Clearly, even partial improvement in the conversion efficiency can have strong economic impact. As the most of energy is now used for the electronics, corresponding scale of the losses forms at the end-user side, where the electricity is converted into a form suitable for a particular appliance. The main effort towards the conversion efficiency improvements therefore targets the area of power AC/DC and DC/DC converters for consumer and industrial electronics. Significant improvement in the conversion efficiency can be achieved by using GaN based transistors, as they are capable to operate at much higher frequencies with almost three times lower switching losses compared to Si devices. The main goal of the project is the research and development of vertical GaN MOSFET without using p-doping, and gaining the original knowledge on electrical and physical properties of the developed devices. From the quantitative point of view, our proof-of-concept device will target RON<2 mOhm/cm2 and VBD>600 V. An original feature of the proposed concept is utilization of the semi-insulating (SI) GaN as a channel layer (instead of p-type GaN), which blocks the current flow through the transistor at zero gate voltage. To open the transistor channel, positive voltage applied to the gate will be needed to induce down bend-bending in the SI GaN, allowing electron injection from the source to the drift region (along the side walls of SI GaN). This concept therefore represents a unipolar enhancement-mode transistor, while drift region is formed of un-doped GaN with extremely low density of dislocation grown directly on GaN substrate.

Contact engineering for advanced materials and devices

Výskum a vývoj kontaktov pre nové materiály a súčiastky

Duration: 1. 1. 2021 - 31. 12. 2024
Program: VEGA
Project leader: RNDr. Gregušová Dagmar DrSc.
Annotation:Intensive research has so far been done into metallic contacts to semiconductors. However, new types of conductivity, materials and devices, and new contact formation mechanisms require new insights into the formation of such contacts. Our aim is to determine the processes and physics behind metallization schemes for normally-off InAlN-based heterostructure high electron mobility transistors with hole conductivity. InAlN with a high molar fraction of InN will be doped with Mg, and the ohmic and Schottky metallic stacks will be optimized. New transition metal dichalkogenide materials (TMDCs) are very promising for new device applications. However, metallization schemes for TMDCs are very challenging. TMDCs exhibit varying band gap widths in dependence of their thickness. Our aim is to study metallization schemes for TMDCs, their topology, and explain differences between ex-foliated and grown samples, and differences between back-gated and top-gated devices in correlation with basic TMDCs properties.

Project leader: Mgr. Zaťko Bohumír PhD
Annotation:Recently, detectors of ionizing radiation are important part of many fields of science and research. The object of proposal is research of various semiconductor detector structures based on Si, GaAs, 4H-SiC and CdTe as a detector of ionizing radiation where 4H-SiC is wide bandgap semiconductor which is radiation resistant material suitable for long term work in harsh environment. This includes optimization of prepared sensor in term of utilization and also what type of radiation will be detected. Also passivation and encapsulation is important in long term word of prepared sensors. The contribution will be also in the simulation due to optimization of size and thickness of sensor contacts and passivation. The prepared structures will be characterized by electrical (curren-voltage and capacitance-voltage measurements) and spectrometric measurements using standartly used radioisotope sources. Also radiation hardness of samples will be tested (increased temperature, ionizing environment).

High temperature superconducting coils in motors for electric and hybrid aircrafts

Vysokoteplotná supravodivá cievka pre motory elektrických a hybridných lietadiel

Duration: 1. 7. 2020 - 30. 6. 2023
Program: APVV
Project leader: Mgr. Pardo Enric PhD.
Annotation:Full superconducting electric motors are very promising to provide the required power density to enable commercial hybrid and electric airplanes. These can reduce emissions by 75 % in CO2 and 90 % in NOx, following the ACARE Flightpath 2050 targets of the European Union. Superconducting motors can also be applied to cleaner sea or sweet water transport. In spite of the extensive research in the area, the electro-magnetic and electro- thermal properties of superconducting coils in the motor magnetic environment remain largely unknown, partially because of the lack of measurements of the relevant temperatures (between 20-40 K) and modeling methods for full superconducting motors. The aim of this project is to gain this understanding and develop numerical modeling methods to enable the design of future superconducting motors. These methods will be compared to experiments in the relevant temperature range for motor applications.

Annotation:The project is focused on the research and development of new types of X-ray optics with highly accurate curved active surfaces. The surfaces will be prepared by an innovative nanomachining technology. We will investigate the application of nanomachining technology to a special case of X-ray optics with curved surfaces, which is a parabolic refractive lens operating in the transmission geometry. The second special case we will focus on will be thin crystal monochromators with different thicknesses in a range of 20-2000 micrometers. Such elements can be used for example as beam splitters in modern X-ray free-electron lasers (XFEL), bent crystals in Johansson monochromators for spectroscopic applications, or they can also be used in particle accelerators for beam steering. The developed elements of curved X-ray optics will be tested in real X-ray metrology and X-ray imaging experiments using laboratory or synchrotron X-ray sources and highly sensitive directly converting X-ray detectors Pilatus and Medipix.
