Characterization of Potential Inhomogeneities on Passive Surfaces by Scanning Kelvin Probe Force Microscopy
Potential mapping measurements have been performed on passive surfaces in air using an Atomic Force Microscopy based technique, the Scanning Kelvin Probe Force Microscope (SKPFM). A linear relation was found between the potential measured this way and the corrosion potential in aqueous solution for a range of pure metals. The SKPFM can be considered to map the practical nobility of the surface....

متن کاملScanning hall probe microscopy technique for investigation of magnetic properties
Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor. SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...
متن کاملScanning Probe Techniques for Engineering Nanoelectronic Devices
microscopy-based techniques is enabling new ways to build and investigate nanoscale electronic devices. Here we review several advanced techniques to characterize and manipulate nanoelectronic devices using an atomic force microscope (AFM). Starting from a carbon nanotube (CNT) network device that is fabricated by conventional photolithography (micron-scale resolution) individual carbon nanotub...
