Witryna3. 1. 5 Impact Ionization. Impact ionization is a typical non-equilibrium process which requires a large electric field. An electron (or hole) in the conduction (or valence) band gains its energy by external electric fields and becomes so highly energetic that it can create an electron-hole pair by colliding with an electron in the valence band and … Witryna18 kwi 2012 · Impact ionization in the drift region also causes the “expansion” effect, which is modeled by making the drift region resistance a function of the impact ionization current in the same region. The new model is verified by comparison with TCAD simulations and experimental data. The interaction between the expansion …
