Laser-induced voltage effects in c-axis inclined NaxCoO2 thin films

► The laser-induced voltage effects in c-axis inclined NaxCoO2 thin films were studied. ► Transverse voltage signals are all observed when the film surface is irradiated by different laser sources. ► Giant transverse voltages of tens of volts are detected when the film surface is irradiated by the UV pulsed laser. ► The c-axis inclined NaxCoO2 thin film has a great potential application in the weak UV pulsed laser detection.
