Methods for depositing III-V compositions on silicon

Patent ·
OSTI ID:1840448
The present disclosure relates to a method that includes directing a first precursor that includes a Group III element and a second precursor that includes a Group V element to a chamber containing crystalline silicon, where the crystalline silicon includes a substantially planar surface that is patterned with a plurality of v-grooves and the directing results in the forming of a III-V crystal preferentially on a (111) Si surface of the crystalline silicon.
