Abstract

The development of semiconductor-based nano- andsubnanosecond high current breakers is crucial for advancingmodern research in experimental physics and radioelectronics,particularly with increasing power (to 1010 W) and repetitionrate (to 104 Hz) of impulse devices. Highlighted in this revieware two types of silicon diodes: drift step recovery diodes(DSRDs) and SOS diodes with the attainable current densitiesand switched-off powers being 102 A cm−2 and 108 W in theformer case, and 105 A cm−2 and 1010 W in the latter. Thepossibility of utilizing not only monocrystalline silicon (as inDSRDs and SOS diodes) for the base material but also monocrystalline silicon carbide is examined.
