Abstract
IT was recently reported1 that certain compounds crystallizing with a triply substituted diamond lattice of the chalcopyrite type are semiconductors. We would report here optically determined energy gaps for a further four such compounds. These, together with the previously reported values for copper indium selenide and copper iron sulphide, are shown in Table 1.
