Low defect density CdTe(111)-GaAs(001) heterostructures by molecular beam epitaxy

Abstract
(111) oriented CdTe has been grown on (001) oriented GaAs substrates by molecular beam epitaxy. Double crystal x-ray diffraction rocking curve and photoluminescence measurements indicate that the CdTe is of exceptional quality despite the large lattice mismatch of 14.6%.
