Abhängigkeit des optischen Bandabstandes von der molaren Zusammensetzung bei Zinksulfid-Kadmiumsulfid-Mischkristallen
Abstract The optical band gap was determined for powder samples of (ZnxCd1-x) S by absorption measurements using a microspectrophotometer. Whereas the lattice constants (measured by X-ray lattice analysis) are linear functions of the components, the band gap is smaller than expected from the molar composition. The relation between band gap and composition was found to be linear, with a break at the equimolar composition. Possible reasons of this phenomen are discussed.
