Complex Heterostructures and Multifunctional Materials

Our research activity relies on highly educated/trained human resources and topmost scientific infrastructure. The HeCoMat team comprises of 33 active members, including 28 with permanent contracts and 7 with short-term contracts. From the 27 members with permanent contracts, 6 are Senior Researchers rank 1 (SR 1), 6 are Senior Researchers rank 2 (SR 2), 7 are Senior Researchers rank 3 (SR 3), 2 are Senior Researchers (SR), 2 are Junior Researchers (JR), 3 are engineers, and another one is technician. From the members with permanent contracts, 21 possess PhD titles (in physics, chemistry, materials engineering or medicine) – including 1 PhD supervisor. Three of the HeCoMat’s team members are PhD students, and 1 is MSc student.

Main research topics:

  • Ferroelectric materials and related structures for electronic, optoelectronic and sensing applications (including non-volatile memories, UV and IR detectors, piezoelectric devices);
  • Materials and devices with applications in microelectronics, photovoltaic conversion and light/particle detection (including field-effect transistors, hybrid perovskite and kesterite solar cells, and silicon-based particle detectors);
  • Superconducting and magnetic materials and strongly correlated electron systems;
  • Dielectric and ferroelectric materials for microwave devices (e.g., dielectric resonators, ferroelectric varactors, filters, antennas);
  • Materials for healthcare applications (prominently for bone regeneration).
