Abstract :
Summary form only given. We have constructed a novel laser ablation chamber dedicated to the production of Ga/sub 2/S/sub 3/-La/sub 2/S/sub 3/ (GLS) films. Sellmier equations and Urbach edge-absorption parameters have been deduced by detailed fitting to experimental data across the entire transparency range (0.6 /spl mu/m to 10 /spl mu/m) of the material. These parameters are required for device design and performance prediction.
