Abstract. The theoretical and experimental investigations of electrical properties of the SiO 2 /Si-ncs/SiO 2 /Si structures grown by high temperature annealing SiO X , X<2, have been carried out. The influence of Si cluster growth conditions on frequency dependences of C-V characteristics, static and dynamic conductance of investigated structures has been clearly observed. As a result of theoretical modeling, C-V dependences have been calculated. The experimentally obtained negative constituent of differential capacitance has been qualitatively described. It has been experimentally found that the SiO 2 /Si-ncs/SiO 2 /Si structures with the tunnel dielectric layer revealed the effect of memorizing.

Keywords: nanocluster, static conductance, dynamic conductance, negative differential capacitance, memorizing effect.
