摘要
The anomalous behaviour of different physical characteristics in vitreous solids compared to the behaviour in the crystalline phase, in particular their dielectric behaviour, can be described by the concept of a system of low-energy excitations in these solids. This concept is also applicable for amorphous SiO2 layers in MOS structures. Thus, a model of breakdown behaviour based on the assumption of the existence of fluctuations of correlated local internal electrical fields and low-energy excitations within these layers is elaborated.
