Non-steady-state photocurrents and holographic recording in indium-oxide (In2O3) thin films

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.
