Grown-in oxygen precipitates in czochralski silicon investigated by transmission electron microscopy;
直拉硅单晶中原生氧沉淀的透射电镜研究
The results revealed that oxygen and carbon concentration of mc-Si had a greater decrease than that of CZ-Si,which means the more oxygen precipitates in mc-Si were generated.
实验发现:经三步退火后,多晶硅比单晶硅氧碳含量下降的幅度大,这表明多晶硅内部形成的氧沉淀多,其体内的高密度缺陷如晶界、位错等对氧沉淀的形成有促进作用。
The behavior of oxygen precipitates in NCZ silicon during the simulated solar cell thermal process was studied by Fourier Transformation Infrared Ray(FTIR).
