|Abstract:||The photo-induced voltage in an individual K enriched MoO 3 nanobundle was studied with localized focused laser beam irradiation. Without an external bias voltage, a significant photo-induced voltage (36.5mV) was produced in a single nanobundle under low laser power (2.2mW). Remarkably, the amplitude and polarity of the voltage could be controlled by the location of the focused laser spot. Unlike the common photo-response that comes from metal-semiconductor junction or PN junction in hybrid nanomaterial, the observed photo-induced effect is from the nanobundle itself, attributed to the small band gap of the material. © 2012 IOP Publishing Ltd.|
