Exposed portions of the substrate are disposed between the mask regions. A plurality of nanostructures are disposed on the exposed portions of the substrate and over the mask regions, the plurality of nanostructures being a single crystal semiconductor and comprising a core tip. An active layer is disposed over the plurality of nanostructures. The active layer is a quantum well structure and comprises at least one material chosen from AIN, AlGaN and GaN. A p-doped layer is disposed over the active layer. Both the active layer and the p-doped layer are conformal to the plurality of nanostructures so as to form an emitter tip over the core tip.

    Abstract: A method for fabricating polymeric sheets containing microwires includes encapsulating at least a portion of individual lengths of a plurality of microwires in a non-conductive polymeric sheet while the microwires are attached to the substrate. The microwires are then detached from the substrate without removing the microwires from the polymeric sheet. The detaching step forms a separated polymeric sheet containing the detached microwires. Individual detached microwires of the plurality are approximately perpendicular to the separated polymeric sheet. A microwire array device includes a non-conductive polymeric sheet and a plurality of microwires. Individual microwires of the plurality have an independent length at least partially encapsulated by the polymeric sheet, are approximately perpendicular to the polymeric sheet, and contain magnetic ferrite.

    Abstract: Provided is a method and system for making powdered Fe16N2. The method can include sealing iron powder and a fixed amount of ammonia (NH3) gas within a pressure vessel. The pressure of the fixed amount of ammonia gas in the pressure vessel can be elevated so that Fe16N2 can be formed from the iron powder. Use of a pressure vessel and a fixed amount of ammonia gas can provide economic and environmental benefits such as higher conversion rates of iron powder into Fe16N2, reduced ammonia gas use, and reclamation of used ammonia gas.
