[交流] 【求助】一名词解释strained single crystal

strained single crystal是翻译成应变单晶吗
什么是应变单晶啊
谢谢各位

谢谢,那应变单晶含义是什么呢,其性能又有什么变化呢?

建议题目可以改成“【求助】名词解释:strained single cystal

可翻译为应变单晶。
由于单晶生长工艺过程中,单晶生长层和衬底会产生晶格匹配误差,从而导致应变。

Strained single-crystal Al2O3 grown layer-by-layer on Nb (110) thin films
Paul B. Welander, James N. Eckstein

(Submitted on 2 Apr 2007)

Abstract
We report on the layer-by-layer growth of single-crystal Al2O3 thin-films on Nb (110). Single-crystal Nb films are first prepared on A-plane sapphire, followed by the evaporation of Al in an O2 background. The first stages of Al2O3 growth are layer-by-layer with hexagonal symmetry. Electron and x-ray diffraction measurements indicate the Al2O3 initially grows clamped to the Nb lattice with a tensile strain near 10%. This strain relaxes with further deposition, and beyond about 5 nm we observe the onset of island growth. Despite the asymmetric misfit between the Al2O3 film and the Nb under-layer, the observed strain is surprisingly isotropic.
