Electric-Field Generation — Material Comparison

← EDC

Poole-Frenkel barrier lowering under a high surface E-field. Pick two materials and an applied field; the engine computes the bulk SRH generation, the field-enhanced generation, and the ratio. The same E-field is applied to both — see which one crosses the breakdown-generation threshold first.

Temperature (K)

E range is log-spaced over 60 points for the G-vs-E curve. The dot on each curve marks the current E input. E-field generation matters most at E > 10⁴ V/cm (typical surface fields in MOS inversion or Schottky depletion).
