Abstract : The pressure dependence of three characteristic energy gaps in ZnTe and one in cubic ZnS was determined over a range up to 10 kilobars of hydrostatic pressure at 77 K. The energy gaps were determined by observation of reflectivity peaks at near-normal incidence. Light from a xenon lamp source was focussed on the cleaved or vapor-grown surface of a single crystal. Re flected light was focussed oentrance slit of a grating spectrograph, and the spectrum was recorded photographically, or by means of a photomultiplier. (Author)
