Electrical properties of TlGaTe2 single crystals under hydrostatic pressure Original Research Article

The effect of hydrostatic pressure (up to 0.82 GPa) on the electric properties of chain TlGaTe2 single crystals has been investigated in the temperature range 77–296 K. It has been shown that pressure leads to a considerable increase of conductivity (σ⊥) across the chains of TlGaTe2 single crystals. Parameters of localized states in the band gap of TlGaTe2 single crystal according to the low-temperature electrical measurements were obtained at various pressures.
