表面迁移 meaning in English

surface migration

These atoms must migrate across the surface to find a crystalographically favorable site .
这些原子必须通过表面迁移以找到一个结晶学上合适的位置。
In addtion , the growth rate of low temperature insb buffer layer was 0 . 26 m / h , which was obtained by rheed intensity oscillation curves . growth temperature of insb epilayers were investigated with sem and dcxrd , and it was found that the optimum temperature was 440 . a 2 . 1 m insb layer grown at 440 had an x - ray rocking curve of 412 arcsec , the strain relaxtion was about 99 . 02 %
