摘要： Exemplary embodiments provide semiconductor devices including high-quality (i.e., defect free) group III-N nanowires and uniform group III-N nanowire arrays as well as their scalable processes for manufacturing, where the position, orientation, cross-sectional features, length and the crystallinity of each nanowire can be precisely controlled. A pulsed growth mode can be used to fabricate the disclosed group III-N nanowires and/or nanowire arrays providing a uniform length of about 10 nm to about 1000 microns with constant cross-sectional features including an exemplary diameter of about 10-1000 nm. In addition, high-quality GaN substrate structures can be formed by coalescing the plurality of GaN nanowires and/or nanowire arrays to facilitate the fabrication of visible LEDs and lasers. Furthermore, core-shell nanowire/MQW active structures can be formed by a core-shell growth on the nonpolar sidewalls of each nanowire.

摘要： Exemplary embodiments provide a scalable process for the growth of large scale and uniform III-N nanoneedle arrays with precise control of the position, cross sectional shape and/or dimensions for each nanoneedle. In an exemplary process, a plurality of nanoneedle array can be formed by growing one or more semiconductor material in a plurality of patterned rows of apertures with a predetermined geometry. The plurality of patterned rows of apertures can be formed though a thick selective nanoscale growth mask, which can later be removed to expose the plurality of nanoneedle arrays. The plurality of nanoneedle arrays can be connected top and bottom by a continuous coalesced epitaxial film, which can be used in a planar semiconductor process or be further configured as a photonic crystal to improve the output coupling of nanoscale optoelectronic devices such as LEDs and/or lasers.
