Published: February 2023
FIG. 1.18 (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 ).

Published: February 2023
FIG. 8.27 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. Reprinted with permission from Li et al., J. Appl. Phys. 131 (1), 015702 (2022). Copyright 2022 AIP Publishing LLC. More about this image found in Temperature-dependent reverse leakage characteristics of a near-ideal β-Ga...
