The device physics of the BSWCNT-based power diodes is unique because the BSWCNT-based power diode has a wide lightly doped layer in addition to a bridged p-n junction with p-type BSWCNT in order to support high reverse breakdown voltage and fast reverse recovery, among others. This layer significantly lowers the ohmic-resistance during the diode's forward conduction state, and stores the electronic charge. In addition, BSWCNT-based-power diode introduces recombination centers in the device to achieve short reverse recovery time, soft recovery, high breakdown voltage and a
low forward voltage drop at the rated forward current.
