Fig. 5: The oxygen vacancy effect on the electron avalanche breakdown process.
From: Dynamic atomic-scale electron avalanche breakdown in solid dielectrics
a Schematic diagram of the oxygen vacancy effect on electron transport behavior. b Variations of the maximum local electric energy of different trap energy levels Wt under the increasing electric field. c Comparisons of the electron avalanche path with Wt of 0.2 and 0.8 eV in Ba-O plane. d Dependences of breakdown strength Eb on Wt and effective density of states Nc in BaTiO3.
