Laser-Induced Graphene on a Polyimide Film: Observation of the Photon Drag Effect

Film structures of porous graphene have been produced by irradiating a polyimide film with focused radiation of a continuous CO 2 laser. The generation of nanosecond photocurrent pulses induced by nanosecond laser pulses in a wide wavelength range has been observed in the obtained structures. It has...

More Information
Summary:Film structures of porous graphene have been produced by irradiating a polyimide film with focused radiation of a continuous CO 2 laser. The generation of nanosecond photocurrent pulses induced by nanosecond laser pulses in a wide wavelength range has been observed in the obtained structures. It has been demonstrated that the photocurrent increases linearly with pulsed laser power and is an odd function of the angle of incidence of radiation on the film structure. The wavelength dependence of the coefficient of conversion of laser power into photocurrent has been measured. The obtained data have been interpreted as a result of current generation due to photon drag effect.
