(a) Simulated electric field profile of the Trench Schottky barrier diode at breakdown voltage of 2.89 kV. (b) The electric field profile along cutline-1 shows that the peak field of 5.6 MV/cm appears at trench corners. (c) Electric field profile along the fin center (cutline 2) shows that the high electric field appears at the trench depth, dtr = 1.1 µm, whereas the near Schottky contact regions experience a reduced surface electric field of Esurf = 0.7 MV/cm. Cutline 3 along the trench center also shows the maximum electric field located at the trench depth (Li et al., 2021).

Temperature-dependent reverse leakage characteristics of a near-ideal β-Ga2O3 SBD. The reverse leakage current (JR) is a sum of TE current (JTE) that captures over-the-barrier current and TFE current (JTFE) that captures below-the-barrier tunneling current under low-to-moderate surface electric fields at the Schottky interface. As the surface field increases or the temperature decreases, the dominant reverse leakage mechanism transitions from TE to TFE.
