Delving into Atomic Force Microscopy Resolution Limits

Wiki Article

Atomic force microscopy (AFM) operates a sharp tip to examine the interface of a sample. This allows for observation at the atomic scale, revealing features. However, there are inherent constraints to the resolution achievable with AFM.

Elements such as tip sharpness, sample characteristics, and imaging settings can all modify the optimal attainable resolution. To reach the highest possible resolution, it is essential to dampen these variables.
