摘要 我们为 26 体积材料的精力损失功能的现在的适合计算,包括 18 个纯元素( Ag ,艾尔, Au , C ,公司, C , Cu ,嗯, Fe , Ge , Mg ,瞬间, Nb , Ni , Pd ,磅, Si , Te )并且 8 混合物( AgCl ,艾尔 <sub>2</sub > O <sub>3</sub>,哎呀, CdS , SiO <sub>2</sub>, ZnS , ZnSe , ZnTe )申请出现电子光谱学分析。试验性的精力损失功能,从测量光数据被导出,基于 Drude-Lindhard 绝缘的模型被适合进公式的有限的和。由检查振荡器力量和和 perfect-screening-sum 规则,我们验证了恰当的结果的高精确性。基于适合的参数,而且,模仿的思考电子精力损失光谱学(卷) 光谱与实验显示出一个好协议。精力损失功能的计算适合参数在 http://micro.ustc.edu.cn/ELF/ELF.html 在一个开、联机的数据库被存储。 We present a fitting calculation of energy-loss function for 26 bulk materials, including 18 pure elements (Ag, A1, Au, C, Co, Cs, Cu, Er, Fe, Ge, Mg, Mo, Nb, Ni, Pd, Pt, Si, Te) and 8 compounds (AgCl, Al2O3, AlAs, CdS, SiO2, ZnS, ZnSe, ZnTe) for application to surface electron spectroscopy analysis. The experimental energy-loss function, which is derived from measured optical data, is fitted into a finite sum of formula based on the Drude-Lindhard dielectric model. By checking the oscillator strength-sum and perfect- screening-sum rules, we have validated the high accuracy of the fitting results. Further-more, based on the fitted parameters, the simulated reflection electron energy-loss spec- troscopy (REELS) spectrum shows a good agreement with experiment. The calculated fitting parameters of energy loss function are stored in an open and online database at http://micro.ustc.edu.cn/ELF/ELF.html.
