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.
