The team at the Semiconductor Physics Department and the Institute of Applied Research, Vilnius University, has a background in the study of optical properties in semiconductors and their nanostructures. The current interests are focused on the investigation of light emission processes on submicrometer scale in semiconductors and structures prospective for LEDs and laser diodes, as well as on plasmonic enhancement in structures with metal nanoparticles. The main spatially-resolved techniques employed are confocal spectroscopy, near field optical microscopy (SNOM), AFM, and SEM. These are supported by luminescence spectroscopy without and with time resolution (in time and frequency domains) in wide ranges of wavelengths and intensities of excitation and in a wide range of temperatures as well as nonlinear optical techniques (light-induced transient gratings, femtosecond pump-probe).
