Abstract
An electrical contact having low electrical resistance and low optical absorption is fabricated on a semiconductor electroluminescent article of III-V semiconductor material having a P-type region and an N-type region contiguous to each other, with a P-N junction therebetween. In the method of forming the contact, Zn is diffused into a surface of the P-type region opposite the PN junction. Then, a layer of gold is evaporated onto the Zn diffused surface while the device is at a temperature of approximately 400.degree.C.
