The newly founded interest association SK Chips wants to contribute to the development of the ecosystem of semiconductor technologies in Slovakia. On Friday 22.11.2024 the constituent meeting of the interest association of legal entities named Slovak Centre for Semiconductors or SK Chips in short took place. The founding members of the association are the Ministry…
This year, we proudly participated in the European Night of Science – Visit Your School – Meet Your Scientist, where we were brilliantly represented by Michal Sobota at Gymnázium na Ul. Ladislava Sáru. Science is not just about theories in textbooks but about the thrilling process of discovery. We believe that our stories, motivation, and achievements can…
Our colleages at Department of Superconductor at IEE SAS uncovered the significant effects of surface scratches on REBCO (Rare-Earth Barium Copper Oxide) superconducting tapes. These tapes, widely used in high-temperature superconductor (HTS) applications, face substantial mechanical stress during manufacturing and operation. The study, published in Physica C, reveals how even minor surface damage can lead…

Superconductors like magnesium diboride (MgB₂) hold significant promise for high-power energy systems, MRI devices, and various industrial applications. A recent study of our colleagues from Department of Superconductors explored how the addition of copper into MgB₂ wire structures improves their thermal stability—a crucial factor for high-current applications. The study compared two types of six-filament MgB₂…
Our student, Mgr. Jana Hrdá, PhD., was awarded the “The STU Rector’s Prize” for excellent performance of study obligations throughout the studies of Doctoral study programme Physical Engineering. The topic of her dissertation was ” Study of the doping effect on the properties of ultra-thin layers of 2D materials.” Congratulations!
Molybdenum disulfide (MoS2) is a frequently studied material due to its layered structure, exceptional properties, and applicability in electronics, optoelectronics, and lithium batteries. In our research, we have shown how the addition of lithium affects the properties of ultrathin MoS2. The layered structure of MoS2 allows the intercalation of foreign atoms into the van der…
Last week (17-21.6.2024) a joint seminar was held with the participation of colleagues from the Industrial Technology Research Institute (ITRI), Slovak University of Technology (STU FEI) and the Institute of Electrical Engineering, Slovak Academy of Sciences (IEE SAS). The opening ceremony held at the STU FEI was attended by representatives of the Slovak Ministry of…
Currently, superconducting conductors are commercially available, and after cooling with liquid nitrogen (temperature – 195 °C), can transmit electric currents ten times higher than classic copper conductors. Without electrical resistance, and thus without energy losses, only direct current can be transmitted. Superconductors have this unique property due to the fact that the passing current is…
