With the help of MDA funding, EMCORE Corporation (145 Belmont Drive, Somerset, NJ 08873; Tel: 732/271-9090; Fax: 732/271-9686; Website: http://www.emcore.com) has developed a GaN-based Schottky diode that can replace the silicon diodes used in a wide range of power supplies. (Schottky diodes are devices that include a layer of metal on top of a semiconductor.) The EMCORE diode offers greater efficiency than silicon, and it costs less than a diode made with silicon carbide (SiC), another high-efficiency alternative to silicon. In other words, EMCORE's diode has the cost of silicon, but with the efficiency benefits of SiC.
Silicon diodes cost less than $1. A diode ...
