Formation of InAs Wires and Dots on Vicinal GaAs (110) Surfaces with Giant Steps by Molecular Beam Epitaxy

View through CrossRef
InAs are grown on vicinal GaAs (110) surfaces with giant steps using molecular beam epitaxy. Atomic force microscopy, X-ray photoelectron spectroscopy and transmission electron microscopy show that uniform and well-aligned InAs wires and dots are formed on the facets at giant step edges due to the accumulation of InAs. This accumulation is only observed in a relatively high growth temperature range (580–600° C) and not at low temperatures.
