Afm resolution limit
WebSince the true resolution limit of AFM imaging is dependent on the geometry of the probe tip, logic dictates that to maintain the highest image quality for the longest amount of time consideration must be taken to preserve tips during and across multiple scans. Contact mode, the most basic AFM operation technique, requires the probe to be ... WebThe theoretical resolution limit of conventional optical imaging methodology (200 to 300 nanometers for visible light) was the primary factor motivating the development of recent higher-resolution scanning probe …
