Cario The optical properties of a GaTa 4 Se 8 single crystal are investigated under high pressure. At ambient pressure, the optical conductivity exhibits a charge gap of ≈0.12 eV and a broad midinfrared band at ≈0.55 eV. As pressure is increased, the low energy spectral weight is strongly enhanced and the ... [Phys. Rev. Lett. 110, 037401] Published Mon Jan 14, 2013
