Description

A scanning tunneling microscope (STM) can be used to obtain images of surface topology with resolution approaching atomic dimensions. It can also be used to measure localized surface energy barriers. The combination of these two features results in scanning tunneling spectroscopy (STS), which can provide barrier-potential maps of solid surfaces. Computer-controlled nanometer probes in general and the STM/STS techniques in particular have important applications in quantitative nondestructive evaluation.
