New results of the transient behaviour of single injection sclc diodes with one deep level

Abstract

It is shown, that only taking into account the time dependence of the local electrical field ℰ(t) yields a complete understanding of the transient behaviour of sclc‐diodes with deep levels. Due to this time dependence of ℰ(t) a rearrangement of the space charge distribution at t = 0 to t → ∞ takes place effecting that at t → ∞ nearly the whole space charge is located within 1/10 of the sample length and that the electric field is equal to U/L in nearly 90% of the sample. The time for the current reaching its steady state value after applying a voltage step is therefore mainly determined by the emission time constant and not by the capture time constant as usually supposed.
