摘要

使用不同光源对掺硼的佐赫拉尔斯基硅中铁-硼（FeB）对的光解离动力学进行了实验研究。结果表明，铁硼解离率不仅取决于综合光强和总体载流子生成率，还取决于照明的光谱成分。解离的材料常数 K 值各不相同，并被确定在 s 范围内。结果表明，重组增强的缺陷反应是对解离第二阶段的主要因素。

Influence of Illumination Spectrum on Dissociation Kinetics of Iron–Boron Pairs in Silicon

Photodissociation kinetics of iron–boron (FeB) pairs in boron‐doped Czochralski silicon is studied experimentally using different light sources. It is shown that the FeB dissociation rate depends not only on integrated light intensity and overall carrier generation rate, but also on spectral composition of illumination. The value of the material constant of dissociation K varies and has been determined to be within s. The investigation reveals an increase in the dissociation rate with increase in photon energy. The results indicate that recombination‐enhanced defect reaction is the primary factor in the second stage of pair dissociation.
