Design space and origin of off-state leakage in GaN vertical power diodes
international electron devices meeting, 2015.
Variable-range-hopping through dislocations was identified as the main off-state leakage mechanism for GaN vertical diodes on different substrates. The behavior of leakage current for vertical devices as a function of dislocation density and electric field was derived by TCAD simulations, after careful calibration with experiments and lit...More
