摘要：

A set of high quality Zn1-xCdxSe/ZnSe quantum well structures with various well widths and Cd contents as well as Zn1-xCdxSe epilayers are grown by molecular beam epitaxy. Their optical properties are investigated by measuring photoluminescence, reflection, and transmission as a function of a vertically applied electric field. The quantum-confined Stark effect is observed at 5 K and a change in transmission of more than 30% achieved at 300 K. By means of numerical model calculations, the underlying electro-absorption and electro-refraction spectra are deduced and the field-induced change of the relevant exciton parameters (resonance energy, oscillator strength, broadening) derived.
