Popis: Results are reported on the current of holes injected into thermally grown SiO2 from a planar avalanching p‐n junction. The current seems to be limited by a bulk process, viz., field‐assisted thermal emission from traps in the SiO2 (Poole‐Frenkel conduction). This mechanism accounts for the exponential dependence of the current on the field in the oxide. From the decay of the current as a function of time, a value of 6 ± 2 cm−1 was found for N0S, the concentration of hole‐trapping centers in the SiO2 times the capture cross section.
