Mechanisms in the Photochemical Growth of Cadmium Mercury Telluride
The role of the various methods of growing cadmium mercury telluride (CMT) for use in the fabrication of infra-red detectors are briefly reviewed so as to identify the present status of photochemical growth of CMT. The fundamental photochemistry of the precursors used, absorption and the thermodynamics of precursor disruption are discussed within the context of photochemically initiated epitaxial growth. The mechanisms of growth that are believed to be active, photosensitisation and free radical processes are analysed together with consideration of potential primary photochemical reactions.
