CdTe-based diode-type X- and γ-ray detectors have a lot of advantages due to excellent characteristics of CdTe semiconductor. Generally, metal electrodes are used to form near-ohmic contacts or a Schottky barrier on the both CdTe faces. To increase a barrier and to obtain various barrier heights on a CdTe-electrode interface, carbon-based electrodes of different properties can be used. In this work, a CdTe-based diode with a carbon-polymer electrode was fabricated. The electrode was made with a carbon-polystyrene layer deposited on the semiconductor surface. Electrical characteristic of the carbon-CdTe structure demonstrated a barrier-like behavior.
