Original abstract

The measurements of local photoluminescence, local photocurrent on GaAs/AlGaAs quantum wells under ambient temperature 300 K have been performed. The level of the locally induced signal in function excitation energy, probe-sample distance and sample position has been studied. The method is relevant to the study of the local defects, to evaluate the aging process of devices.

Czech abstract

Bylo provedeno měření lokální fotoluminescence, lokálního fotoproudu na GaAs/AlGaAs kvantových jamách při pokojové teplotě. Byly studovány úroveň lokálně indukovaného signálu v závislosti na excitační energii, vliv vzdálenosti hrot-vzorek. Metoda je relevantní ke studiu lokálních defektů a k hodnocení procesu stárnutí součástek.
