摘要
A depth profiling technique is described for molecular beam epitaxy grown (Al,Ga)Al/GaAs heterostructures which combines photoelectrochemical layer-by-layer removal with analyses by photocurrent spectroscopy. The technique is illustrated for two types of samples having a graded and "flat" Al profile in the epilayer.
