• 論文の詳細を見る

• Optical absorption spectra of layered compound GaS are measured near theindirect edge under uniaxial pressure parallel to the c-axis (perpendicular to thelayer) at 4.2 K. The deduced values of the deformation potential for the indirectedge are D'. = - 8.0 42.5 eV and Df7= - 2.3 .[.0.4 eV for the strain perpendicularand parallel to the c-axis, respectively. The sign and anisotropy of the deforma-lion potentials obtained here are discussed on the basis of the band model charac-teristic of layered materials, where the competition between interlayer and intra-layer interactions determines the pressure dependence of their band gaps.
