Abstract: 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.

Abstract: 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.

Abstract: A data encoding system having means for generating decodable data representing a facsimile number to which a document containing an image is to be sent via facsimile, a rasterizer for rasterizing the image of the document and the decodable data to generate raster data, a decoder for decoding the data after the decodable data is rasterized by the rasterizer to determine the facsimile number to which the document is to be sent, and facsimile means for sending the raster data to the facsimile number determined by the decoder. The decoder comprises a permanent memory having stored coding data which includes character data representing a plurality of characters and a unique binary code associated with each of the characters. The decodable data generator comprises a permanent memory having font data stored therein for representing each of a plurality of characters.

Abstract: Apparatus is disclosed for distributing image data borne on a selected one of a plurality of documents in response to a data request message identifying said selected one document. The data request message is transmitted by a data requestor over a transmission medium, e.g., typical telephone lines, to the distributing apparatus. The distributing apparatus comprises an addressable memory for storing the plurality of documents. A processing circuit, e.g., a voice board, receives said data request message over the transmission medium and provides address signals corresponding to the selected one document to the memory to read out document image signals therefrom corresponding to the selected one document. A further processing circuit, e.g., a fax board, is connected to the to receive the document image signals for generating and transmitting over the transmission medium to the data requestor a return message bearing image data of the selected one document.
