Abstract: JBS diodes based on 4$H$-SiC irradiated with electrons and protons are studied. This is carried out by using the methods of capacitance–voltage and current–voltage characteristics. It is concluded that, for both kinds of irradiation, deep centers are formed in the upper half of the band gap of silicon carbide. This leads to a sharp decrease in the concentration of ionized carriers in the conduction band and to an exponential increase in the resistance of the base regions of the structures under study.
Keywords: Radiation-induced Defects, Capacitance Voltage, Diode Base, Current Voltage Characteristics, Initial Doping Level.
