Department of Semiconductor
Materials Engineering

The scientific activity in our department is focused on the physics and engineering of semiconductor materials, hybrid semiconductor heterostructures and devices. We are particularly interested in the development of advanced methods for semiconductor research, as well as in the application of standard methods for efficient diagnostics/characterization of semiconductor materials and devices. Our main experimental tools are modulation spectroscopy (photoreflectance, electroreflectance, piezoreflectance, …), photoluminescence and time-resolved photoluminescence, time-resolved microwave photoconductivity, photoacoustic spectroscopy, deep level transient spectroscopy, X-ray diffraction and others. Many experiments are performed under high hydrostatic pressure. By using these tools and methods, we aim to perform the most sensitive and accurate measurements on semiconductor samples provided by external collaborators, in order to achieve a comprehensive understanding of their properties. Our experimental studies are supported by theoretical calculations (DFT and kp method calculations).

Our goal is to understand the physical phenomena in the studied semiconductor materials/heterostructures and publish new results in scientific articles as well as disseminate these results in the scientific community.

Currently, our research focuses on van der Waals crystals, hybrid organic–inorganic perovskites, and hybrid semiconductor heterostructures.
