Abstract

A combination electrothermal (ET) mechanism of ionization of neutral centers is demonstrated to exist. The corresponding ionization coefficient is calculated and conditions at which the ET mechanism becomes dominant in the process of ionization of neutral centers are elucidated. Investigations show that the ET ionization mechanism leads to an increase in the free-charge carrier density in the pre-breakdown state and for a low compensation factor reduces the breakdown electric field intensity, thereby leading to better agreement with the experimental data.
