Physical properties at the contact semiconductor - Gas discharge plasma in a thin gas discharge cell

In this work, we investigated the physical properties at the contact of a semiconductor made of single-crystal cadmium telluride with a gas discharge plasma. It is shown that the charge carriers in the plasma, along with the incident infrared radiation, contribute to the enhancement of the photocurrent in the gas-discharge cell. At sufficiently high voltages (more than 2.5 kV), a positive feedback is observed in the gas-discharge cell associated with the action of the plasma on the semiconductor surface.
