Abstract

BALASUBRAMANIAN, A.K.; SANKAR, N.  and  RAMACHANDRAN, K.. On the phase transformation of CdS to CdCO₃ by photoacoustics. Superf. vacío [online]. 2006, vol.19, n.1, pp.8-11. ISSN 1665-3521.

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.
