Strong field effects in MOS systems containing compensated donors and traps distributed in energy

The current-field temperature relationships of the Ta-Ta₂O₅-MnO₂ system are studied when the tantalum has positive polarity. It is demonstrated that the conductivity of such systems is determined by the Poole-Frenkel effect (PFE) for partially compensated donors. We compare our results with previous results [9]. A theory of the PFE is developed for a model which includes traps with an exponential energy distribution; acceptors, and deep discrete donors.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 10, pp. 3–6, October, 1981.
