The electrical properties of Cd-doped GaSe have been investigated by using Hall-effect and deep-level transient spectroscopy (DLTS). The temperature dependence of hole concentration shows the characteristic of a partially compensated p-type semiconductor. The moderately deep acceptor level at about 0.28 eV above the valence band is detected by using both Hall-effect and DLTS measurements. We find that the acceptor level is associated with Cd-related defects formed by the dopant atoms.
