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.
