Deep Ultra-Violet (DUV) Light Emitting Diodes

Abstract

Problems to Overcome: The main problem to overcome is to develop a commercially and economically viable method to synthesize and process high crystalline quality diamond films for applications such as DUV LEDs and solar-blind detectors. Scientific Approach: The scientific approach is the homoepitaxial deposition on diamond films on large area (50 - 100 sq mm) synthetic Type Ib diamond substrates. Although type Ib diamond substrates have a high nitrogen content (100-300 ppm), they typically have low density of dislocations which makes them ideal for homoepitaxial film growth. In Phase I, the company will demonstrate high quality, large area crystalline films, while in the Phase II we propose to demonstrate DUV LEDs/detectors using large area diamond manufacturing technology.
