PEROVCHIR – Effect of the application of organic molecules on the properties of perovskite thin-film structures
Vplyv aplikácie organických molekúl na vlastnosti perovskitovských tenkovrstvových štruktúr
Registration code:	APVV-23-0238
Program:	SRDA
Project leader:	RNDr. Španková Marianna, PhD
Annotation:	In recent years, sufficient experimental evidence has accumulated that adsorbed organic chiral molecules affectthe superconducting properties of YBa2Cu3O7-x (YBCO) films. In some cases, an increase in their critical temperature Tc can be observed. On the other hand, it has been shown that in the case of ferromagnetic layers (e.g., cobalt), the application of chiral molecules can lead to a change in magnetization without the use of an electric current. An important role here is played by spin. Spin introduces an additional degree of freedom into the system, allowing devices, for example, to reduce electrical consumption or increase their computational capacity. Spintronic devices have become an attraction in electronics; however, problems associated with controlling spin remain a significant challenge. A unique way of manipulating spin is through the effect known as chirality-induced spin selectivity (CISS), which results from the specific structure of organic chiral molecules. The project focuses on the preparation and characterization of simple heterostructures and their interaction with chiral polymers deposited on the film surface. Specifically, it deals with the influence of chiral lactic acid on perovskite thin films, where the selected perovskites are high-temperature superconductor YBCO and ferromagnet La1-xSrxMnO3 (LSMO).

PIRADUNEW – Perspective ionizing radiation detectors for the uncovered neutron energy window
Perspektívne detektory ionizujúceho žiarenia pre nepokryté energetické okno neutrónov
Registration code:	APVV-22-0382
Program:	SRDA
Project leader:	Mgr. Zaťko Bohumír, PhD
Annotation:	The subject of the presented project is the optimization and preparation of semiconductor detection structuresbased on 4H-SiC and polycrystalline diamond suitable for neutron detection. As part of the project, single detectorswill be prepared and investigated, especially for neutron energies from 100 keV to several MeVs. There arecurrently few sensitive detectors in this area of neutron energy. The advantages of SiC and polycrystalline diamond are the high radiation and temperature resistance of structures. The high spectrometric capability of SiC detectors is also important, especially when detecting neutrons with energies below 1 MeV. Polycrystalline diamond is m ore affordable than SiC, and our first preliminary results show its promising detection properties, especially when detecting ionizing particles. Another advantage of both types of semiconductors is the low sensitivity to gamma radiation, which is almost always present in the event that neutrons are formed during a nuclear reaction. This gamma ray enhances the background and impairs the sensitivity of the detectors currently in use. Pixel sensors for the Timepix/Medipix reading chip will also be developed and investigated. Prototypes of the radiation camera will be tested and calibrated using a monoenergetic neutron source.

Registration code:	09I03-03-V02-00044
Program:	Plán obnovy EÚ
Project leader:	Mgr.Phil. Ahmad Faizan
Annotation:	Two-dimensional (2D) materials, including transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2) or platinum diselenide (PtSe2), are one of the promising materials and a gateway to modern technologies and optoelectronics. Currently, there is a lot of research that studies fabrication of TMDs by chemical vapour deposition (CVD), which makes the use of these 2D materials in the electronic market feasible. The use of alternative methods such as pulsed laser deposition (PLD) also opens up new possibilities in this field and can provide comparative results to elucidate the growth optimization. The available CVD and PLD systems in IEE SAS will be used to study the fundamental aspect of the growth and properties of TMD materials. For research-related activities, the optimized TMD layers are typically grown on standard 1×1 cm2 substrates. However, from a technological point of view, upscaling the fabrication process is a big challenge. Many times, the deposition conditions (temperature, gas flow, pressure, power, etc.) used for small-scale samples preparation may not work well on a larger scale. Thus, the study and optimization of large-scale (4-inch) fabrication will be a new chapter in this interesting field of 2D materials research. The PhD thesis will be focused mainly on the development of technological procedures for the preparation of precisely defined, homogeneous and reproducible TMD layers on large areas using a newly installed two-zone furnace. In addition, a comprehensive characterization of the surface and bulk properties (including morphological, chemical, optical and opto-electronic properties) of the fabricated 2D materials is also expected.

Annotation:	Thanks to the unusual physical properties, 2D materials have been intensively studied for several years. Aninteresting group of this class of materials is transition metal dichalcogenides TMD. They have a hexagonalstructure with the individual layers bonded to each other only by weak Van der Waals bonds. This causessignificantly anisotropic properties and has a significant effect on their electronic structure. Some of them showphysically interesting correlated states (superconductivity, charge density waves). The primary goal of this projectis to prepare and study the properties of thin layers of 2 different TMD – MoS2 and PtSe2, and to study theinfluence of doping with Li and Na cations on the electrical and structural properties of these layers. Thesecondary goal is to optimize growth and doping conditions to improve the parameters of thin films, such aselectrical conductivity and charge carrier mobility which will enable the preparation of functional electroniccomponents – transistors.
