我们的AFM型号是DIMENSION ICON，

Peakforce QNM求弹性模量的步骤忘记怎么操作了，想问一下有没有这一模式的操作说明，或者步骤。谢谢

请在您的D盘 Manuals文件夹中查找004-1036-000_PEAKFORCE QNM USERS GUIDE。

孙公您好，这个帮助手册有。不明白怎么根据公式求杨氏模量E

force-seperation曲线已经做出来了，不知道在这个曲线上怎么求相应的参数

如Ftip，d等

附件是PeakForce QNM的离线处理说明，您可以参考一下如何由力曲线信息求得杨氏模量。

孙博士您好，按照您给我的离线处理的说明书看过后。发现，我导出的XZ坐标和你的说明书上的那种曲线差别较大，这种图导出的XZ坐标怎么去求杨氏模量呢，按照你给的说明书做不出来。这种曲线就是做不出来还是我做的有问题呢，谢谢孙老师指导

请问是通过High Speed Data Capture捕捉的图像吗？看您的图应该不是，纵坐标应该是deflection error或者force，不应该是Peakforce deflection。在PeakForcetapping中直接得到的力曲线没有经过低通滤波处理，针脱离表面时的振动会被记录下来。所以你会看到那些振动。

是在QNM模式下点击capture line，然后得到的图。在下面两图图在获取数据过程中都出现过，是不是还要设置某些参数？还是样品太软的原因？孙老师

需要High Speed Data Capture的图，不行的话您把得到的*.hsdc的数据发到我邮箱。
