Abstract

We investigated the crystalline structure of Ge1-x-ySixSny layers epitaxially grown on Ge(001) substrates. The unstrained and compressive strained Ge1-x-ySixSny layers with very flat surface and high crystallinity can be grown. We found that the control of the strain direction is important to form a high quality Ge1-x-ySixSny layer even with small misfit strain.

Ge1−x−ySixSny层在Ge(001)衬底上的外延生长和晶体性质
我们研究了在Ge(001)衬底上外延生长的Ge1-x-ySixSny层的晶体结构。可以生长出表面非常平整、结晶度高的非应变和压缩应变的Ge1-x-ySixSny层。我们发现应变方向的控制对于形成高质量的Ge1-x-ySixSny层非常重要,即使错配应变很小。
