Delving into Atomic Force Microscopy Resolution Limits

Wiki Article

Atomic force microscopy (AFM) operates a sharp tip to scan the surface of a sample. This allows for visualization at the atomic scale, revealing patterns. However, there are inherent constraints to the resolution achievable with AFM.

Factors such as tip sharpness, sample traits, and imaging conditions can all affect the maximum attainable resolution. To reach the highest possible resolution, it is essential to reduce these variables.

One key factor is tip geometry, which directly impacts the dimensions of features that can be resolved. Sharper tips are necessary to achieve sub-nanometer resolution.
