低能电子衍射 meaning in Chinese

low energy electron diffraction
low-energy electron diffraction (leed)

Low electron energy diffractometer lee
低能电子衍射仪
Low energy electron diffraction
低能电子衍射
By carefully checking the leed pattern , it is found that the " ( 2x2 ) " pattem is actually a combination of the c ( 2 x 2 ) reconstruction from the ersi , island surfaces and the ( 2x l ) reconstruction from the bare si substrae
对（ x2 ）再构的低能电子衍射的仔细研究表明，实验中观察到的px2 ）再构实际上是来自于饵硅化物的叶x2 ）再构与来自硅表面的cxi八门2 ）再构的迭加产物。
The ultra - thin er layers with the thicanesses in the range of 0 . 5 ~ 3 monolayer ( ml ) are formed by electron beam evaporation on si ( 00l ) substrate at room temperature in an ultra - high vacuum system . after annealing at lower temperatures , ordered simcfores form on the surface . the trallsition of the surface reconsmiction pattem from ( 2 x l ) to ( 4 x 2 ) with the increase of er coverage up to l ml is observed by the reflective high energy electron diffraction ( rheed ) and low energy electron diffraction ( leed )
本文是关于硅( 001 )衬底与电子束淀积的铒、铪原子反应形成的超薄膜的界面与表面性质的研究，以及在该衬底上出现的共振光电子发射现象，包括了以下四个方面的工作： 1铒导致的硅( 001 )衬底上的( 4 2 )再构研究利用反射高能电子衍射和低能电子衍射，在室温淀积了0
