This extended Poole-Frenkel model includes the effects of compensation. The relative densities of donor and acceptor sites control the slope of the log J vs E1/2 plots. With only one type of site present, the slope equals that expected for Schottky emission slope= (e3/πεε0)1/2/2kT. When sites of the opposite type compensate, the slope doubles. The degree of compensation must be known to determine the barrier heights separating the emission site from the band edge. Data from metal-silicon nitride-metal devices are consistent with this model with emission occurring from impurity sites approximately 2.0 eV from the conduction band edge.
