TL;DR: In this paper, photoacoustic spectroscopy was used to study the band-gap shift effect of CdS films, which were grown by chemical bath deposition and exposed to different annealing atmospheres over a range of temperature.
Abstract: We study by photoacoustic spectroscopy the band‐gap shift effect of CdS films. The CdS films were grown by chemical bath deposition and exposed to different annealing atmospheres over a range of temperature in which the sample structure changes. We show the band‐gap evolution and resistivity as a function of temperature of thermal annealing and determine the process that produces the best combination of high band‐gap energy and low resistivity.
