Semiconductor lasers, LEDs and laser structures mainly for mid-infrared wavelengths.
GaN based scintillators and HEMTs. Epitaxial techniques (from LPE and MBE to MOVPE, currently) for preparation of hetero-nano-structures for quantum wells and quantum dots from III/V elements (namely InAs/GaAs a In(Al,Ga)N/GaN). Characterizations of optical, electrical and structural properties of semiconductors with respect on practical applications.
