摘要：

Optical absorption and photoconductivity of new chalcogenide amorphous SeTe/CdSe superlattices of pnpn type are investigated. The optical absorption coefficient α changes stepwise with the variation of the intensity and duration of the illumination. The analysis of the experimental results indicates the formation of subbands in the conduction and valence band. The essential role of the indirect transitions at sublayer thickness below 100 Å is discussed. © 1992.
