Thermionic emission or tunneling? The universal transition electric field for ideal Schottky reverse leakage current in $\beta$-Ga${}_2$O${}_3$

Wenshen Li, Kazuki Nomoto, Debdeep Jena +1

The reverse leakage current through a Schottky barrier transitions from a thermionic-emission dominated regime to a barrier-tunneling dominated regime as the surface electric field…
