Abstract:
In this paper the effects of high energy (3.0 MeV) electrons irradiation over a dose ranges from 6 to 15 MGy at elevated temperatures 298 to 448 K on the current-voltage characteristics of 4$H$-SiC Schottky diodes were investigated. The experiment results show that after irradiation with 3.0 MeV forward bias current of the tested diodes decreased, while reverse bias current increased. The degradation of ideality factor, $n$, saturation current, $I_{s}$, and barrier height, $\Phi_{b}$, were not noticeable after the irradiation. However, the series resistance, $R_{s}$, has increased significantly with increasing radiation dose. In addition, temperature dependence current–voltage measurements, were conducted for temperature in the range of 298 to 448 K. The Schottky barrier height, saturation current, and series resistance, are found to be temperature dependent, while ideality factor remained constant.
