摘要
Electrochemical crystal growth of hollandite-type CsxTi8O16 was examined employing high-temperature electrolysis of a molten mixture consisting of TiO2 and Cs2MoO4 with constant applied voltages. The resultant needle-like crystals showed obviously distinct appearances, either optical transparency or metallic luster, depending on the applied voltage. While the transparent crystals were electrical insulators, the metallic luster crystals were moderately conductive, with rho-T curves being fitted with the one-dimensional (1D) VRH model, suggesting that the compound is a 1D metal involving carrier localization.
