七、峰面积比(Peak Area Ratio) 峰面积比是XPS中常用的定量分析方法之一。通过比较不同元素的峰面积比值,可以获得元素的含量信息。但峰面积比法的前提是峰形相同,且峰面积与元素含量成正比。因此,在使用峰面积比法进行定量分析时,需要进行峰形校正和基底修正。 结论: 半导体XPS参数是影响分析结果准确性和可靠性的...
Cu2p3 / 2 and Cu 2p1 / 2 two peaks is the peak-demand orbit splitting, so that the two peak area ratio is fixed: 3:2 relationship. Fitting these two peaks in the time, you can lock the two peak area ratio, so that the fitting was reasonable. 翻译工具翻的,楼主参考一下吧。 赞...
