The project is intended to address the following issues: study of the precipitation dynamics of oxygen as well as the oxygen structural state in Si with different defect concentration and type; establishement of the interrelation between the concentration and type of these microdefects on the one hand and the formation dynamics and the structure of oxygen precipitates on the other hand; establishement of the mechanism of the formation of structural defects in oxygen containing Si during the crystal growth and subsequent anneals; elaboration of the physical model of the precipitation processes of oxygen in the single crystalline Si that takes into account the influence of the concentration and type of microdefects. Multi-stage furnace and beam anneals are applied for the modification of the defect state of crystal. The basic methods of investigation are IR-spectroscopy, high-sensitivity X-ray diffractometry and topography, optical and transmission electron mkicroscopy, determination of the diffusion length and life time of minority charge carriers, computer simulation.
