Patent ID: 8664094

Claim:
A method of growing nitride based semiconductor nanowires, comprising: growing a plurality of Group III-nitride nanowires by chemical vapor deposition (CVD) in a nanowire growth step, wherein a nitrogen source flow and a metal-organic source flow are present; forming at least one Group III-nitride shell layer on each of the plurality of Group III-nitride nanowires by CVD in a shell growth step, wherein the nitrogen source flow and the metal-organic source flow are present; and forming a continuous Group III-nitride layer over the at least one Group III-nitride shell layer and continuously covering all of the plurality of Group III-nitride nanowires, wherein: a molar V/III-ratio comprises a molar ratio of the nitrogen source flow rate and the metal-organic source flow rate; the molar V/III-ratio during the shell growth step is higher than the molar V/III-ratio during the nanowire growth step; the at least one Group III-nitride shell layer comprises an active region of a light emitting diode (LED); the plurality of Group III-nitride nanowires are doped one of n- or p-type; and the continuous Group III-nitride layer is doped another one of p- or n-type to form a junction with the plurality of Group III-nitride nanowires.
