Abstract
Abstract This letter reports on the formation of hillocks on epitaxial GaAs prepared by reacting trimethylgallium (TMG) and arsine. Layers were grown over a wide range of As : Ga ratios (4 : 1 to 15 : 1) in the gas phase. Hillocks were observed at growth rates in excess of 0.5 μm/min, irrespective of the gas composition.
