查询词典 lattice structure

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。
