How is the resolution power of atomic force microscopy determined?

[JayKo]

how to determine the resolution power of it? has it got anything to do with correlation wavelength? just wondering how it is calculated?

 

[Andy Resnick]

The resolution (in the scanning plane) usually depends on the tip geometry- how sharp the tip is, and how well one can deconvolve the tip shape.

Hi Andy, thanks. i see, but the experiment asking how to improve resolution power? i suppose using a slower scan rate and slow tip velocity would do the tricks. on the other hand. isn't it the resolution = scan size / sample per line? similar to the dot per inch resolution? btw, are you relative of Robert Resnick? just curious.

No relation.
