Semiconductor materials are widely used in optoelectronics devices such as light emitting diodes (LEDs) and infrared detectors.
Light Emitting Diodes
Blue LEDs used in white light applications are typically made from gallium nitride and its ternary alloys with indium, aluminum etc. New materials such as ZnO and ZnSe are currently being studied for the next generation LEDs.
We provide MOCVD equipment for GaN and ZnO research as well as our HCl Dry Etcher to support multiple MOCVD machines in LED production.
HgCdTe (mercury cadmium telluride, MCT) is the most commonly used
