Abstract: We report resistivity and thermo-electric power measurements of the anatase phase of TiO₂under pressure up to 2.3 GPa. Despite its transparent appearance, the single crystal of anatase exhibits a metallic-like resistivity above 60 K, at all pressures. The rather high value of the thermo-electric power at room temperature points to complex transport mechanism in this phase.

Keywords: transparent semiconductor; resistivity; thermo-electric power
