摘要
A model is developed of field (tunnel) generation of positive charge in thermal silicon dioxide of Si-SiO//2 structures under high electric fields. The main characteristics of accumulated charge, i. e. kinetic DELTA U//F//B(t), depth and current-time dependences, etc are numerically simulated. It is shown that the model satisfactorily explains some experimentally observed facts and the mechanism of tunnel ionization must be taken into account, when charge accumulation in dielectrics under high field condition is investigated.
