Gain Processes in ZnTe Epilayers on GaAs

Abstract: Optical gain processes in ZnTe epitaxial layers grown by MOVPE on GaAs substrates are reported. Depending on the excitation conditions, optical gain related to exciton-exciton scattering or due to recombination in an electron-hole plasma is identificd by means of the variable-stripe-length method. The experimental gain spectra are compared to model calculations for the respective gain processes. Stimulated emission up to room temperature is observed under intense picosecond excitation.Optische Verstarkungsproz… Show more

“…ZnTe is an interesting II-VI semiconductor material used in optoelectronic devices, such as in photovoltaic elements [1,2], green light-emitting diodes [3], broad-frequency field sensors [4,5], waveguides [6,7], and gain media [8,9]; some of these devices take advantage of nanoscale effects [10]. ZnTe also has nonlinear optical properties [11].…”
