砷化镓表面RHEED图谱的LabVIEW设计

RHEED Patterns of Gallium Arsenide(GaAs) Surface Designed by LabVIEW

本文在LabVIEW 8.2开发环境下,通过对反射式高能电子衍射仪(RHEED)原理及样品砷化镓GaAs(001)_a(2×4)结构模型的表面原子结构进行深入探究,编程设计实现了理论情况下的GaAs(001)_a(2×4)表面原子结构RHEED图谱。该阶段性成果使有关虚拟RHEED实验系统课题的研究进一步深入,课题最终成果将具有双重意义。

Under the development environment of LabVIEW 8.2,through exploring the principle of （Reflection High Energy Electron Diffraetion）RHEED and the atomic structure of the sample Gallium Arsenide GaAs（O01）_ a（2×4） structural modelsurface in depth,this paper programmed,designed and implemented the RHEED patterns of GaAs （001）_a （2×4） surface atomic structure in theory circumstances.The staged production makes the study on the subject about virtual RHEED equipment system further in-depth.And the ultimate production of the study has a dual significance.
