    Abstract

    This report pertains to the synthesis, crystal growth and characterisation of the infrared detector materials - mercury cadmium telluride (MCT) and lead tin telluride (LTD in a composition suitable for use in the 8-14 mew wavelength region. The procedures adopted for the crystal growth of MCT and LTT and the methods used for characterising the crystals for homogeneity of composition, dislocation density, energy band gap, intrinsic carrier concentration and carrier mobility are described. The results obtained from these studies are discussed. These studies indicate the suitability of these cystals for detector applications.
