Abstract
The quantum-confined Stark effect (QCSE) in Zn1-xCdxSe/ZnSe multiple q uantum wells embedded in the intrinsic region of p-i-n photodiodes has been investigated by means of photoluminescence spectroscopy under ap plied bias and photocurrent spectroscopy. Room-temperature excitonic b leaching is observed at reverse biases as low as 3 V. Both the redshif t and the reduction of the oscillator strength of the excitonic emissi on have bean calculated by means of a variational model. We use the sa me model to clarify the main specific features of the QCSE in II-VI ma terials.
