Abstract:
A method for sequential epitaxial growth of a III-V compound on a non-native substrate to provide an epitaxial film, comprising the steps of:a) arranging a substrate within a HVPE reactor;b) forming, by HVPE at a growth temperature, an epitaxial layer on the substrate to provide a III-V/substrate sample;c) removing the III-V/substrate sample from the reactor;d) arranging the III-V/substrate sample within the HVPE reactor;e) forming, by HVPE at the growth temperature, an epitaxial layer on the III-V substrate sample;f) successively repeating steps c) through f) until the epitaxial film has attained a desired thickness; andg) cooling the epitaxial film to ambient temperature, wherein the multi-layer epitaxial film remains entire when cooled to ambient temperature.
