We present the idea of using a buffer layer of deviation from stoichiometry for materials growth on large lattice mismatch substrates. This idea was realized in nitrides growth in this thesis.

首次提出了采用偏离化学计量比的缓冲层在大晶格失配的衬底上生长单晶膜的思想，并在GaN外延生长上得以实现。

However, because of the lattice mismatched and imperfect band structure, the application of Si〓Ge〓/Si heterojunction has been constrained. The incorporation of carbon into Si〓Ge〓 layer, provides an additional degree of freedom in Si-based band and strain engineering.

然而，通常外延生长的Si〓Ge〓/Si结构是一种晶格失配异质结，受到临界厚度的限制，而且也不具备理想的能带结构，限制了其进一步的应用。C掺入Si〓Ge〓合金，为Si基能带工程和应变剪裁提供了新的自由度。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
