scanning tunneling microscope advantages and disadvantages
But before purchasing any SEM, new or used, a couple of questions need to be answered. How a STM Works. Scanning Tunneling Microscopy (STM) is a new technique in microscopy that works without requiring any focusing elements and can achieve high resolution on the atomic scale, both laterally and vertically. The invention deserved Nobel prize for physics in 1986. By: Simran. An electron microscope utilises electron beams to enlarge an object while a light microscope uses light rays to magnify any object.
