Magnesium diboride (MgB2) is a promising superconductor for many applications. One of the advantages of this material, is that it is possible to join single or multi-core MgB2 wires using MgB2 joint, obtaining a connection with very low or zero electrical resistance suitable for persistent mode operation of devices, such as high field superconductor magnets….
Colleagues from the gallium oxide group led by Dr Filip Gucmann in cooperation with the HUN-REN Centre for Energy Research and Łukasiewicz – Institute of Microelectronics and Photonics have organised two-day workshop on WBG/UWBG #semiconductor materials and devices in Budapest to disseminate the results achieved during the implementation of the CUBES project funded by the…
Silicon carbide (chemical name silicon carbide, SiC) is a promising semiconductor material suitable for use as an ionizing radiation detector. It is highly radiation resistant and also chemically and thermally stable. Due to their advantageous properties, SiC-based sensors are mainly applicable in environments with high temperature and also ionizing radiation intensity. We prepared pixel sensors…
High-temperature superconductors, such as Magnesium diboride (MgB2), are enabling materials for building state-of-the-art high-field magnets, which will provide new findings in many fields of physics. One of the hurdles in the development of superconducting magnets is a “persistent switch”. Persistent switch is a joint in superconducting magnet, which after cooling down to cryogenic temperatures lowers…

The development of quantum computers is currently facing a crucial technological challenge: how to scale existing systems from a few hundred quantum bits (qubits) to millions on a single chip. Spins of elementary charges confined in quantum dots are considered a promising candidate for scaling qubits, mainly due to their compact size but also for…
Scientists from the Institute of Electrical Engineering of the Slovak Academy of Sciences (IEE SAS) have introduced a new electro-thermal modeling method for superconductors, offering higher accuracy and efficiency compared to previously used approaches. This method, called METEP (Minimum Electro-Thermal Entropy Production), brings significant advantages over traditional methods. Unlike the traditional finite difference method, METEP…
How stable are gallium oxide layers at high temperatures? Scientists from the Institute of Electrical Engineering of the Slovak Academy of Sciences set out to answer this question. Their research provides crucial insights into a promising semiconductor material – gallium oxide (Ga₂O₃) – which has attracted significant interest from both scientific and industrial communities due…
On February 18, 2025, we officially opened the Scientific Café at the Institute of Electrical Engineering SAS, v.v.i. This newly created social space, which also serves as a kitchenette, is designed to enhance the daily work environment and foster informal communication among colleagues. Why a Scientific Café? Great ideas often arise not only in laboratories…
On February 19, 2025, the Institute of Electrical Engineering of the Slovak Academy of Sciences (IEE SAS) hosted the seminar “Innovations in Thermal Management for Modern Power Electronics,” co-organized with TechSim, the leading SIEMENS partner in CEE. The event aimed to present the latest technologies and approaches in thermal management for power modules and to…
