Abstract :
It has been experimentally found that structures with Si-nanoclusters grown by ion-plasma sputtering method revealed the effect of dynamical memorizing. The negative constituent of differential capacitance for these structures has been clearly obtained. Electric properties of structures with Si-nanoclusters and parameters of interface states located between Si-nanoclusters and SiO2 were studied in detail by measuring of frequency and temperature dependences of C-V characteristics.
