ultra-high vacuum system 中文意思是什麼
ultra-high vacuum system
解釋
超高真空系統-
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 )
