Research objectives

The laboratory's objective is to study the optical and electronic properties of semiconductor materials and semiconductor nanostructures in wide spectral and temperature ranges, applying and developing modern spectroscopic methods and optimizing new materials for optoelectronic, renewable energy and biomedical applications.

Main research areas:

1. Spectroscopy of quantum semiconductor nanostructures

Optical studies of quantum wells, dots, and superlattices in the UV-NIR spectral range and 4-300 K temperature range, using modulation spectroscopy and photoluminescence spectroscopy.

2. New complex, semiconductor materials and heterostructures

Studies of the optical response and electronic structure of bismides and other advanced materials in the UV-NIR spectral range. Characterization of surface nanostructures and photovoltaic systems.

3. Advanced biomedical imaging methods

Development and application of spatiotemporal optical coherence tomography for in vivo retinal imaging and biopsy specimens, optimizing early diagnostics of neurodegenerative diseases.
