Abstract
Photocurrent-spectroscopy studies were performed in the 10<T<300 K tem perature range on p-i-n heterostructures grown by molecular-beam epita xy and incorporating Zn1-xCdxSe/ZnSe multiple quantum wells (with x=0. 10 and 0.25) in the undoped region. The extremely well-resolved excito nic features and corresponding continuum edges allowed us to obtain di rectly the exciton binding energies and compare the spectra with excit onic transition energies calculated taking into account the effect of strain.
