ZnMgSeTe Light Emitting Diodes

Materials Science Forum, 1994
The MBE growth of light emitting diodes based on junctions between n-ZnMgSe and p-ZnMgSeTe is reported. For optimized compositions of the n- and p-layer, doping levels as high as n=p=2×1018 cm−3 were obtained. The p contacts of these diodes are ohmic, and the voltage needed to achieve a given current density is comparable to that of the best ZnSe based

Light Emitting Diodes

Electronics and Power, 1976
The light emitting diode (i. e. d. ) is widely used as indicator lamp, and in displays. The output covers a narrow spectral band which is defined by the material and dopants used. At present red, orange, yellow and green emitting devices are commercially available. The l. e. d. has many of the expected attributes of semiconductor devices including long
