FEMSIM + HRMC:非晶态材料的涨落电子显微镜模拟和结构细化

FEMSIM+HRMC: Simulation of and Structural Refinement using Fluctuation Electron Microscopy for Amorphous Materials

Jason J. Maldonis, Jinwoo Hwang, Paul M. Voyles

摘要:

FEMSIM是一个Fortran程序,可以模拟电子显微镜信号的涨落,即方差V(k),从一个模型原子结构中模拟出来。FEMSIM已被纳入一个混合反向蒙特卡罗程序,结合嵌入原子或Finnis-Sinclair势与模拟和实验V(k)数据之间的偏差,以细化原子模型的结构约束的潜力和实验数据。由此产生的模型具有实验导出的中程秩序。

英文摘要:

FEMSIM, a Fortran code, has been developed to simulate the fluctuation electron microscopy signal, the variance, V(k), from a model atomic structure. FEMSIM has been incorporated into a hybrid-reverse Monte Carlo code that combines an embedded atom or Finnis-Sinclair potential with the deviation between simulated and experimental V(k) data to refine an atomic model with structure constrained by both the potential and experimental data. The resulting models have experimentally-derived medium-range order.
