摘要
介绍一系列峰形修正的方法——包括本底的扣除、仪器响应函数的修正、非弹性散射影响的消除等,并将其应用于Si(100)表面的俄歇峰形分析中,对于L_(23)VV,L_1L_(23)V峰取得了与理论计算符合很好的结果,从中可以提取出丰富的价带局域电子态信息。
Methods for the correction of Auger lineshape are presented, including background subtraction, deconvolution by instrumental broadening functions and energy loss function. By applying the above processes to the measured Si(100) L_(23)VV and L_1L_(23)V Auger lineshape, we have obtained a good agreement with theoretical results. It is shown that informations related to the local density of states (LDOS) and chemical states can be acquired by employing Auger lineshape analysis(ALA).
