Low voltage carrier injection in ZnSe-based blue-green laser diodes on p-type GaAs substrates with InGaAlP band offset reduction layers

Summary form only given. A low voltage current injection is demonstrated theoretically and experimentally for ZnSe/CdZnSe blue-green lasers. Insertion of InGaAlP layers reduce the excess voltage drop, due to the large valence band offset between the p-type GaAs substrate and p-type ZnSe layer. The InGaAlP layers are also useful as high concentration p-type ZnSe layers can be grown on them.
