Abstract
The results of Portillo et al. (Superfices y Vacío 15, 19-21, 2002) on the phase transition in CdS are analysed entirely by a different route here. With CdS single crystal taken in wafer form, photoacoustic measurements are carried out in the presence of carbon and air. Phase transformation from CdS to CdCO3 is obtained at a temperature of 80°C which agrees well with the results of Portillo et al.
Keywords: Photoacoustic spectroscopy (PAS); CdS; Thermal diffusivity.
