We succeeded in distinguishing between oxygen and silicon atoms on an oxygen-adsorbed Si (111)7 x 7 surface, and also distinguished between silicon and tin atoms on Si (111)7 x 7-Sn intermixed and Si ...
The dispersion forces between atoms and nanostuctures have been measured by using a scanning probe microscope in which the tip is a confined gas of ultracold atoms. Dispersion forces operate on a wide ...
