CV characteristic evaluations of GaN-MOS have revealed the presence of a large number of hole traps. This raises concerns about reliability, such as threshold fluctuations, in power devices. When deep traps are present, the time constant is long, making it impossible to reproduce actual measurement results with conventional DC calculations. Device simulations allow for comparison with actual measurements through transient calculations assuming SRH statistics. This report examines the behavior of CV characteristics with hole traps using transient numerical simulation and compares it with measurement results.
