摘要：
The distribution of the conduction-band tail states in a Zn0.3Cd0.7Se II-VI semiconductor alloy has been determined experimentally using persistent photoconductivity (PPC) transient measurements, and is confirmed to be exponential. Our results show that the transport properties in II-VI semiconductor alloys are strongly influenced by tail states caused by alloy disorder. A class of transport properties in disordered systems that may be probed by PPC measurements have also been proposed.
