How is the resolution power of atomic force microscopy determined?

Click For Summary

Discussion Overview

The discussion revolves around the determination of the resolution power of atomic force microscopy (AFM), exploring factors that influence resolution, including tip geometry and scanning parameters. Participants inquire about the relationship between resolution and various experimental conditions.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions how to determine the resolution power of AFM and suggests a possible connection to correlation wavelength.
  • Another participant states that resolution in the scanning plane typically depends on the geometry of the tip, particularly its sharpness and the ability to deconvolve the tip shape.
  • A different participant proposes that improving resolution could involve using a slower scan rate and tip velocity, while also relating resolution to scan size and sample per line, drawing a parallel to dot per inch resolution.
  • A participant clarifies that they have no relation to a mentioned individual, Robert Resnick.

Areas of Agreement / Disagreement

The discussion contains multiple competing views regarding the factors that influence resolution power, and no consensus has been reached on the best methods to improve it.

Contextual Notes

Participants express uncertainty about the exact calculations involved in determining resolution power and the implications of different scanning parameters.

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

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.
