The composition study of the oxidized PS layer after Al-film coating has been shown by STM, STS (with tunnel I-V curves) and IR-spectroscopy to be the self-organized Si nanocrystallite. Si_xO_y:Si_zO_yAl or Si-nanocrystallite: Si_xO_y nanocomposites. The electronic properties (tunnel current, capacity, differential capacity relaxation) are determined by the presence of Si-nanocrystallites with size of 2,5-4 nm, and band gap E=2,4-2,8 eV surrounded by the matrix consisting of SiO, SiO_2, Si_2O_3 and Si_xO_yAl nanooxides.
