Click For Summary
The resolution of a Scanning Tunneling Microscope (STM) is closely related to the size of its tip, which is typically a single protruding molecule. Under ideal conditions, this allows the STM to detect the positions of individual molecules. The discussion suggests that the ratio of resolution to tip size is approximately 1:1. Participants are seeking formulas or links to better understand this relationship. Accurate calculations are essential for optimizing STM performance in molecular imaging.

does anyone have a link or a formula for calculating the resolution of a STM based on the tip size.
 
Physics news on Phys.org
According to this link and a couple others, the tip of a STM is a single protruding molecule and, under ideal conditions, can record the possition of individual molecules.

So I geuss the ratio of resolution to tip size is about 1/1.
