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

摘要

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