Abstract
We have studied the energy band structure of uniaxially compressed single crystals K2ZnCl4. The smallest direct energy-gap for the stress-free crystal is 4.55 eV and corresponds to the Γ-point of the Brillouin zone. The pressure coefficients for the energy positions of the valence and conduction band states and the band gap are determined. The pressure-induced decrease in the band gap found by us correlates well with the increase of the refractive indices known from the earlier experiments.
