Abstract This work describes a discharge system for heating and evaporation of a boron powder target based on a non-self-sustained arc discharge with a filament, a hollow cathode and a hot combined anode. The measurements of the current-voltage characteristics of the discharge with a hot anode and the dependence of the anode temperature on the discharge parameters are presented. The modes of deposition of boron films have been determined.

Self-heating in high-voltage 4H-SiC PiN diodes has been studied experimentally and theoretically in dc and 8-ms single pulse modes. To simulate the self-heating, an electro-thermal model was used to calculate non-isothermal current-voltage characteristics at dc and current-time dependences at pulsed measurements. The dynamic instability of N-type was observed: the current decreases in spite of increasing of bias applied to the structure. At dc, irreversible diode degradation was found to occur at a current density of about 1700 A/cm2. Under a single current surge 8-ms pulse, the loss of thermal stability has been found at a current density of approximately 9000 A/cm2. Comparison of experimental data and simulations showed that the local temperature in the diode base at the end of the 8-ms, 9000-A/cm2 pulse reaches 2000 – 2300 K.
