Paper Abstract

The design of quantum logical elements based on nanocrystalline silicon was made. The optical properties of polycrystalline silicon films with oxygen incorporation in grain boundary were experimentally studied. The Raman scattering, photoluminescent and Fourier-transformed infrared spectra were measured. The different kinds of defects were detected. The E' and D centers was measured by electron-spin resonance method. The triplet state of oxygen was detected by fourier-transform infrared spectroscopy. The hyperfine structure of oxygen level in A-center was detected by laser picosecond spectroscopy. It is assumed that the splitting of oxygen level is caused due to the ultrasound oscillation of oxygen atom in A-center. We propose the qubit based on A-centers in polycrystalline oxidized silicon.
