摘要
We calculate optical gain coefficient and threshold current density in ZnS/MgBeZnS quantum wells (QWs) because ZnS/MgBeZnS QWs are useful for the fabrication of an ultraviolet laser on zinc-blende substrates. The threshold current density in a ZnS/MgBeZnS QW laser diode (LD) with a 10 nm ZnS active layer is calculated to be 1.63 kA/cm2. By comparing the measured Jth in a CdZnSe/ZnSSe/ZnMgSSe QW LD with that calculated by us, it is expected that the threshold current density in ZnS/MgBeZnS QW LDs measured by experiment is larger than that calculated by our calculation method.
