We report on the growth and photoluminescence (PL) characterization of ZnMgCdSe quaternary quantum wells (QW) imbedded in ZnMgSe barriers containing 35% Mg. The ZnMgSe alloys have been recently suggested as alternative base materials for blue light e

The valence band offset between ZnMgSe and ZnTe is studied as a function of the Mg content. The band alignment was deduced from photoluminescence measurements on multi-quantum-well structures consisting of alternated layers of Zn 1-x Mg x Se and ZnTe

ZnMgSe has been suggested as an alternative base material for blue light emitting diodes. For the optimization of such devices the strain state of the active layer is a very important parameter to be considered, since it has recently been considered

A PD (partial-discharge) diagnosis system is presented that gives information about the location of any detectable PD source in a GIS (gas-insulated-substation) testing unit. For every detected impulse the system measures and processes the apparent c

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 diode

One of the main problems for the fabrication of optoelectronic devices in the blue spectral range is the limited p-dopability and the resulting high contact resistivity of p-ZnSe. We show that the admixture of even small Te fractions to ZnSe has a st
