Silicon-Based Blue Light Emitting Diode
Abstract
The overall goal of this program is to fabricate stable green/blue 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
