Abstract

A Nd:YAG LASER operating at 1.064 m was used to deposit CdS thin films on glass and GaAs (100) substrates. Depending on the sub-strate temperature, the as-deposited films were either cubic or hexagonal dominant. At a substrate temperature of approximately 200°C, predominantly cubic structured films were grown while at approximately 400°C the hexagonal phase was formed. The films were in the stoichiometric ratio of 1:1 for Cd:S. The surface of the films were optically smooth. Optical transmission revealed the room temperature absorption edge for the cubic films was close to 515 nm, and that of the hexagonal films was approximately 500 nm. At a temperature of 10K, the absorption edge of the cubic film was 502 nm. Raman spectrum studies revealed the locations of the first two longitudinal optical (LO) modes for the cubic films were close to that of the hexagonal films.
