Abstract

Comparative study between the poly-Si and the poly-SiSn layers reveals that the Sn incorporation is effective to decrease the crystallization temperature. Also, we found that the formation of SiSn polycrystal with a substitutional Sn content of around 30%, which is expected as a direct transition semiconductor, becomes possible on SiO2 at a low temperature growth of 150°C.

在绝缘层上低温生长高锡ssi多晶
通过对聚硅层和聚sisn层的对比研究,发现Sn的掺入对降低结晶温度是有效的。此外,我们还发现,在150℃的低温生长条件下,在SiO2上形成取代锡含量约为30%的SiSn多晶,有望成为直接过渡半导体。
