Abstract:

The overall goal of this program is to fabricate stable greenblue electroluminescent devices based on nanostructures of Si alloyed with group IV such as carbon and germanium. During the past two years, optically excited visible-light emission from electrochemically etched anodized silicon has provided researchers with the possibility of fabricating a red-to-orange LED based on porous Si. A few groups have used semi-transparent gold as a solid state contact to porous Si to form Schottky diodes. Spire, under a SDIO funded SBIR program, has demonstrated a light-emitting device consisting of a heterojunction between electrochemically etched p-type porous Si and n-type transparent indium tin oxide ITO. The use of ITO or other wide-bandgap semiconductors which are transparent to visible light has potential applications for visible LEDs and display panels
