Abstract: A light emitting device is disclosed comprising a bottom layer of electrically conductive material. A block of electrically insulating material is disposed on the bottom layer. At least a portion of the block is optically transparent. A top layer of electrically conductive material is disposed on the block. A plurality of discrete nano-crystals of a material selected from the group consisting of Group IV, Group III-V, and Group II-VI is disposed within the block, and are thereby electrically insulated from the top and bottom layers. Also provided are bottom and top electrodes connected to the bottom and top layers, respectively, for applying a voltage therebetween.

Abstract: A field effect transistor and method for making is described incorporating self aligned source and drain contacts with Schottky metal-to-semiconductor junction and a T-shaped gate or incorporating highly doped semiconductor material for the source and drain contacts different from the channel material to provide etch selectivity and a T-shaped gate or incorporating a metal for the source and drain contacts and the oxide of the metal for the gate dielectric which is self aligned. The invention overcomes the problem of self-aligned high resistance source/drain contacts and a high resistance gate electrode for submicron FET devices which increase as devices are scaled to smaller dimensions.

Abstract: A method of forming a semiconductor structure, includes steps of growing an oxide layer on a substrate to form a first wafer, separately forming a metal film on an oxidized substrate to form a second wafer, attaching the first and second wafers, performing a heat cycle for the first and second wafers to form a bond between the first and second wafers, and detaching a portion of the first wafer from the second wafer. Thus, a device, such as a back-plane for a semiconductor device, formed by the method includes an oxidized substrate, a metal film formed on the oxidized substrate forming a back-gate, a back-gate oxide formed on the back-gate, and a silicon layer formed on the back-gate oxide.
