Gallium nitride (GaN)-based semiconductors are increasingly used for the fabrication of highly efficient power converters. Our colleagues have succeeded in confirming the functionality of an original concept for a vertical power transistor. Modern GaN power transistors with lateral channel geometry are gradually commercialized and used in electronic industry. Compared to this concept, the vertical geometry…

August 23, 2023 at 10,00 a.m. Ing. Ondrej Pohorelec Supervisor: RNDr. Dagmar Gregušová, DrSc. Theme: Názov: Hole channel GaN-based transistor for power electronics Abstract: This dissertation thesis deals with threshold voltage instabilities in normally-off transistor with unintentional hole channel and a preparation of InAlN/GaN transistor with intentional hole channel. Theoretical parts summarize properties of the…
During the visit of the Slovak-Taiwanese Commission for Economic Cooperation, representatives of the Institute of Electrical Engineering Slovak Academy of Sciences (ElÚ SAV) signed a license agreement and a memorandum of understanding with the Industrial Technology Research Institute (ITRI), Taiwan. Under the license agreement, the IEE SAS will build-up a laboratory for reliability analysis of…
Spontaneous symmetry breaking is a physical phenomenon when some system decides to choose one of several options in an unpredictable way. For example, an egg placed on its tip will roll to the side. If it was placed on the tip precisely, it is not possible to predict in advance which side it will roll…
Composite conductors based on high-temperature REBCO (rare-earth cuprates) superconductors reach high transport current densities (1010 [A/m2]) at liquid nitrogen temperatures (‑193 ˚C), which makes them good candidates for high-field magnets (tens of Tesla). That makes them an interesting option for high-power cables, magnetic resonance, nuclear magnetic resonance, etc. In contrast to standard copper wires, which…
