Hexagonal boron nitride (h-BN), an ultra-wide band gap semiconductor (~5.9 eV), emerges as a promising candidate for high-power electronics. Despite its potential, the development of h-BN-based power devices faces significant challenges related to contact formation. In this study, we employ our established contact formation technique and demonstrate the rectifying properties of h-BN through the NiAu/h-BN:C/graphite vertical structure.
