Abstract: A nondestructive approach is described that is applicable for studying the In-segregation phenomena in ultra-thin In(Ga)As/GaAs nanostructures grown by molecular beam epitaxy. The proposed method utilizes only the experimental photoluminescence (PL) spectroscopy data and the… read more here.

DOI: 10.3103/s1062873817120218
Abstract: Terahertz wave propagation in thin semi-insulating GaAs plates is studied by means of timedomain terahertz spectroscopy. It is found that when terahertz radiation is focused on the edge of a crystal plate, a series of… read more here.
