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 imaging at the atomic scale, revealing structures. However, there are inherent boundaries to the resolution achievable with AFM.

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