Thermodynamics and kinetic theory of nucleation and the evolution of liquid precipitates in gallium arsenide wafer
We study nucleation and evolution of liquid droplets in semi-insulating solid gallium arsenide (GaAs). For a realistic modelling, the crucial issue of a combined thermodynamic and kinetic treatment is [...]
PAM-XIAMEN offers 650nm laser diode (LD) wafer, which emits red visible light. The epi wafer for laser diode 650nm from us is composed of the epi layers: P+ GaAs, P- AlGaInP, undoped AlGaInP, undoped GaInP QW, undoped AlGaInP and N- AlGaInP, deposited on the [...]
