SiC formation on ribbon surfaces grown by the capillary action shaping technique via vapor phase deposition is reported. This deposition is very active during the seeding phase and during the initial growth period of the ribbon. Such films degrade th

The influence of oxygen on the minority carrier lifetime of silicon is reported. Bulk annealed, oxygen-rich crystals subsequently sliced into wafers show lifetime degradation with annealing time. Silicon oxide precipitates and punched out dislocation

It is shown that the minority carrier lifetime τ in silicon can be reduced effectively by doping with cesium. A lifetime value of 2.2 × 10−10 s can be achieved by implantation of 1013 Cs+/cm2 at 200 keV and subsequent anneal in nitrogen followed

The electrical and structural properties of dendritic silicon have been measured and compared with solar cell efficiencies. The twin planes in the web and their effect on minority carrier diffusion length were of particular interest. The starting mat

Silicon ribbons 0.5 mm in thickness were grown by a capillary action shaping technique using graphite capillary dies. Ribbons up to 1.3 m in length and 12 mm in width were obtained. Crystallographic ribbon perfection was studied through X-ray topogra

Directional solidification of silicon in carbon crucibles was achieved by using two variations of the Bridgman-Stockbarger method. One was a static technique wherein liquid silicon in a carbon crucible was positioned in a tamperature gradient of abou

Computer simulation leading to controlled large diameter Czochralski crystal growth is discussed. A simple mathematical model, which describes the different crystal growth phases including neck‐in, fast flat top, roll‐over to constant diameter bu
