Optical Phonons in Laser-Deposited CdSxTe1-x Films

Research output: Contribution to journal › Article › peer-review

Abstract

We report the longitudinal optical (LO) phonon frequencies for thin films of the ternary alloy CdSxTe1-x and their composition dependence for the full range of x values from pure CdTe to pure CdS. Pulsed laser deposition was used to prepare the photocrystalline thin films including composition well inside the miscibility gap. We find that this ternary system ehibits a 'two-mode' behavior withCdS- and CdTe-like longitudinal optic phonon modes. The modified random-element isodisplacement model yields a good description of the composition dependence of the LO phono frequencies.
