Abstract

Indium-oxide thin films present interesting electrical and optical properties and high potential for technological applications. The conductivity of indium-oxide thin films grown by dc-magnetron or laser sputtering can be modified upon illumination with ultraviolet radiation (photon energy > 3.5 eV), resulting in a variable electrical state of the films from a resistive to a purely conductive one. While recently holographic recording has been demonstrated [1] aiming to information storage and processing applications. We report simultaneous measurement of the non-steady-state photoelectromotive force [2] and holographic recording in indium-oxide thin films at the He-Cd laser wavelength of 325 nm (Fig.1). Two He-Cd laser beams formed a holographic grating in the thin film. One of the beams was phase modulated at frequency omega was detected by and a HeNe laser beam was monitoring the holographic recording. Two scattered beams of equal intensity were observed, corresponding to the + or - 1 diffraction orders of the recorded sinusoidal grating, and monitored. The non-steady-state photocurrent J. The combination of the above methods provides a powerful tool for the investigation of holographic properties in this material.
