Current research focus

The main subject of our studies is the interaction of impurities in semiconductors and how it affects semiconductors properties. We develop our research in two ways: experimental and theoretical. Our experimental studies are mostly concerned on photoluminescence spectroscopy of doped semiconductor structures. In our theoretical research we widely use a high performance numerical simulation using multi-task programming when possible. The group leader Pavel Petrov is a lecturer at Polytechnic University participating in "Smart Nanostructures and Condensed Matter Physics" master's program.
