Patent ID: 8084337

Claim:
A method of growing at least one III-V semiconductor nanowire from a Si surface, the method comprising a step of providing a group III material pre-flow at a predetermined elevated temperature to provide a (111)B-like group III material-terminated Si surface prior to growing of the III-V semiconductor nanowire; wherein the III-V semiconductor nanowire is grown by particle assisted growth and the method comprises the steps of: providing the group III material pre-flow at the predetermined elevated temperature giving diffusion of group III material into a growth catalyst particle to provide the (111)B-like group III material-terminated Si surface; introducing group III material and group V material precursors at a high temperature to grow a thin III-V nucleation layer with (111)B orientation; lowering the temperature; and growing said at least one III-V semiconductor nanowire from the nucleation layer at the lowered temperature.
