孙老师,

您好!

我想请问一下LiftMode 和 Interleave mode的这两者的区别,尤其是应用上。

Manual对这两种模式的说明:

LiftMode: During the interleave scan, the feedback is turned off and the tip is lifted to a user-selected height above the surface to perform far field measurements...

Interleave Mode: the feedback is kept on while additional topography, phase lateral force, or data is acquired.

我想知道LiftMode所指的feedback是不是只是topography?而Interleave mode里面的feedback是不只两套feedback?

谢谢!

Teddy

Interleave mode 可以用另外一套setpoint和gain等参数去实现另一次在表面上的扫描,lift height在此模式中不起作用,在interleave line上,对形貌的反馈始终是打开的。主要的应用:如果在加电扫描形貌时发现不太好,或者获得性质图与获得形貌图需要的最优参数不同,可以使用此种模式。比如可以在做cAFM时,主扫描线扫形貌,lnterleave扫描线扫电流;在做TR-TUNA时,主扫描线扫形貌,lnterleave扫描线扫电流等等。

Lift mode是先记住主扫描线的形貌,在此基础上抬高lift height的高度(也可以是负值),关掉对形貌的反馈,进行第二次扫描,主要用于磁力显微镜,静电力显微镜以及表面电势测量等等。
