“…hotoconductive semiconductor switches (PCSSs) have gained extensive attention due to their advantages over conventional gas and mechanical switches, such as high breakdown field, fast switching time, compact geometry, inherent optical isolation, negligible jitter, and high thermal conductivity [1][2][3][4][5][6][7][8]. A promising candidate for PCSS is semiinsulation silicon carbide (SiC), and the wide bandgap materials have high critical electric field strength (>2 MV/cm), high electron saturation velocity (>2.0×10 7 cm/s), and thermal stability characteristics (3-5 W/(cm•K)) [9][10][11][12][13].…”
