【Epitaxy Papers】Carrier transport and electronic defects in gallium oxide studied by photoconductivity techniques

      Researchers from the University of Strathclyde have published a dissertation titled "Carrier transport and electronic defects in gallium oxide studied by photoconductivity techniques" in Journal of Physics: Conference Series.

Abstract

      Two complementary localised density of states spectroscopies, Modulated Photo-Conductivity (MPC) and the Constant Photocurrent Method (CPM) are applied to Ga₂O₃ thin films and are shown to be sensitive to carrier traps above and below the Fermi level, respectively. These techniques measure the film directly, without requiring a Schottky or p-n junction, which may offer advantages over conventional techniques in the study of high-resistivity or semi-insulating materials. The benefits of a higher-resolution MPC analysis are demonstrated.
