A Review on Conduction Mechanisms in Dielectric Films
Figure 25
Carriers distribution in dielectric film under carrier weak injection () in space-charge-limited conduction. (a) Very weak injection (, , ), (b) dielectric relaxation and carriers redistribution, and (c) weak injection at (, , ). is the transition voltage at the onset of departure from ohm’s law; is the concentration of injected carriers; is the concentration of thermally generated free carriers in dielectric film; is the carrier transit time; is the dielectric relaxation time.
