Light emitting diode technology can be applied to lightweight radar display equipment. Use of this technology requires an understanding of the diode types, light output, and current drain. Broad area silicon P-N junction diodes were operated under reverse biased conditions in the avalanche region. The light spots, or microplasms, that developed were observed and the relationship of the diode light intensity to the diode current was determined. Microplasm breakdown on the P-N junction during avalanche occurs at randomly positioned breakdown sites and the thresholds for microplasm ignition differ from site to site. The electric field required for microplasm appearance are greater than 120 kVcm. Author
