Scanning Tunneling Microscopy

In Scanning Tunneling Microscopy (STM) a metallic tip is placed above a substrate at a height on the Angstrom scale determined by applying a small voltage to the tip and stabilizing the resultant electron current between the tip and the substrate. Lateral scanning and readjustment of the tip height generates a topographic image of the substrate that can resolve individual atoms, molecules and surface defects. We apply this technique to a number of different surface phenomena indicated on the right (a click on the topics provides examples).
