摘要

利用射频溅射样品实验证明了非晶态Si/SiO2多层膜在热退火过程中硅纳米晶的形成与层厚的依赖关系,并通过改进的模型进一步解释了这一点。理论计算表明,硅层厚度存在一个下限(1.5nm),硅纳米晶体的横向生长不受约束。

Layer-thickness-dependent formation of Si-nanocrystals embedded in amorphous Si/SiO2 multilayers
Layer-thickness dependence of Si-nanocrystal formation in amorphous Si/SiO2 multilayers during thermal annealing is experimentally demonstrated with RF-sputtered samples, and further explained by a modified model. The theoretical calculation shows that there is a lower limit (1.5nm) of Si layer thickness and lateral growth of Si-nanocrystal is unconstrained in such multilayers.
