Electronic conduction along the [001] direction of a faceted anatase TiO 2 particle in contact with two tungsten probes is found to be an order of magnitude higher than that along the [010] direction due to a smaller potential barrier of the TiO 2 (001)–tungsten interface for electron transport than the TiO 2 (010)–tungsten interface. This finding could guide the design of TiO 2 ‐based electrodes.
