A semiconductor/environment interface has been formed in which suspended silicon nanowires (SiNWs) are in direct contact with photoactive TiO 2 quantum dots. The photoactivity of TiO 2 competes with the intrinsic photoresponses of p‐type silicon nanowires. Rational control of the competitive mechanism realizes remarkable mirror‐imaging photo‐switching and superior rectifying effects in a single SiNW‐based device.
