Name: Institute of High Pressure Physics, PAS

Description:

The Institute was founded in 1972 by splitting from the Institute of Physics PAS as an independent Laboratory of High Pressure Semiconductor Physics headed by prof. Sylwester Porowski. Semiconductors are still the dominant field of research currently focused on III-V nitrides. The first GaN crystals in the world were obtained under high pressure in our Institute. It was an impulse to create a modern Center of Physics and Technology (Strategic Infrastructure GaN-Unipress), in which crystal growth, epitaxial quantum structures (MOVPE and MBE) as well as optoelectronic and electronic devices are studied. In addition, we have developed nanotechnologies based on solvothermal synthesis and extreme plastic deformation, as well as soft matter physics that is used in food processing (Strategic Infrastructure X-PressMatter). Over 100 researchers and doctoral students lead here their fascinating research using high pressure as an important physical variable. A unique scientific equipment is constructed at the Institute to help us to achieve original and well-recognized research results. The Institute is interested in commercialization of its scientific results (6 active spin-offs created).
