Abstract: An alternative way to characterise composition modulation in InxGa1−xP ALMBE layers grown on GaAs (001) substrate at a temperature of 420 °C by selective etching and photo etching is presented for the first time. AFM and TEM examinations revealed characteristic quasi-periodic surface structures consisting of ridges oriented along [110]. We propose that morphology features observed in the experiments are related to composition modulation effects.
