LT GaAs semi-insulating layers applied in vertical-cavity surface-emitting lasers
In this paper we report on the optimization of the MBE growth process for obtaining semi-insulating LT-GaAs layers applied in vertical-cavity surface-emitting-lasers. The technological conditions for growingLT-GaAs layers have been found and test processes for growing the laser structure [...]
