We report on a novel semiconductor photoelectrode structure that exhibits a dependence of the photocurrent-voltage characteristics on the concentration of a nonadsorbed, outer-sphere redox acceptor. The structure consists of a thin (30–50 A) epilay

We present a rigorous analysis of the effects of electric fields on time-resolved photoluminescence spectra in semiconductors. It is based on the solution of the semiconductor transport equations using the drift-diffusion approxmation. The results sh

The relaxation dynamics of photoexcited charge carriers at the interface between InP and several metal ion solutions has been studied using picosecond time-resolved photoluminescence and electrochemical techniques. The results show that for p-InP, th
