Abstract
The structure of the atomic arrangement at the apex of the tip plays a n important role in the atomic force microscope (AFM) images. Computer topographs of the sample surface were simulated with various tip stru ctures at the apex. We have described a scheme to estimate the lower l imit of the lateral resolution of AFM with a mono-atomic tip. It is ob served that in the contact mode of operation, resolution and sensitivi ty of AFM is comparable to that of STM.
