Epitaxial growth of CdSe has been achieved on GaAs(111) by electrodepositio
n from an aqueous electrolyte. The structure of the film corresponds to the
cubic modification of CdSe. The quality of epitaxy has been investigated b
y reflection high energy electron diffraction, transmission electron micros
copy and X-ray diffraction techniques. By XPS measurements the chemistry of
the CdSe/GaAs interface and the composition of CdSe are determined. (C) 20
