Patent ID: 8652947

Claim:
A method for growing non-polar III-V nitride materials comprising: (a) providing a template material comprising a layer of non-polar III-V nitride semiconductor material; (b) creating a mask on top of the template material; (c) using the mask to form a plurality of independent nanocolumns, comprising non-polar III-V nitride material, in the template material, the nanocolumns each having a diameter between about 10 nm and 300 nm, and each nanocolumn having a tip portion on the distal end thereof, the tip portion being defined by the diameter of the nanocolumn and a length that characterizes a distance that the tip portion spans in a direction parallel with the central axis of the nanocolumn; (d) subjecting the nanocolumns to a passivation process wherein a passivation layer is formed on at least one nanocolumn, wherein the passivation layer does not cover at least the tip portion of the nanocolumn; and (e) growing a non-polar III-V nitride semiconductor material only onto the tip portion of the nanocolumns, such that the non-polar III-V nitride semiconductor material is not present on other portions of the nanocolumns.
