چکیده انگلیسی
Using low-temperature scanning tunneling microscopy/spectroscopy we have developed a method for measuring electrostatic potential in high spatial and energy resolutions, and performed a real-space observation of the potential screened by two-dimensional surface electrons around step edges, where extra charges are localized, on the Si(1Â 1Â 1)â3Â ÃÂ â3-Ag surface. In the potential images, characteristic decay and the Friedel oscillation were clearly observed around the charges.
