拉长的晶粒 meaning in Chinese
elongated grain
Examples
- Sem , transmission electron microscopy ( tem ) , x - ray energy - dispersion analysis ( edax ) , xrd , electron diffraction ( ed ) and high - resolution electron microscopy ( hrem ) were used to investigate the morphology , atomic composition and crystal structure of the nanowires . the hexagonal cdse nanowires with single crystal structure have been obtained in dmso under 140 . ( 3 ) semiconductor te and cdte nanowires embedded in aao templates were fabricated for the first time by dc < wp = 7 > electrodeposition in ethylene glycol
Sem 、 tem 、 edax 、 xrd 、 ed 、 hrem分析的结果表明，所得cdse纳米线为六方晶型，晶体的（ 001 ）晶面沿平行于基底的方向择优生长，且随沉积温度的降低，这种择优生长的趋势越来越强；纳米线晶体在生长时，由于受aao模板孔径的限制，形成c轴方向拉长的晶粒，其长径比达5 1以上；晶体的大小和完善程度随沉积温度的降低而增大， 185沉积得到多晶六方cdse纳米线，而140沉积时可得到六方cdse单晶纳米线。
