the scanning electron microscope
it is only thirteen years since the scanning electron microscope has been available commercially. yet, even in this short period of time, this instrument has been a powerful tool in the investigation of topography, electrical and magnetic properties, crystal structure, cathodoluminescent characteristics etc. of solid specimens. today, this type of microscope has opened its place alongside the c...
متن کاملTunneling rates in electron transport through double-barrier molecular junctions in a scanning tunneling microscope.
The scanning tunneling microscope enables atomic-scale measurements of electron transport through individual molecules. Copper phthalocyanine and magnesium porphine molecules adsorbed on a thin oxide film grown on the NiAl(110) surface were probed. The single-molecule junctions contained two tunneling barriers, vacuum gap, and oxide film. Differential conductance spectroscopy shows that electro...
متن کاملTheory of the scanning tunneling microscope.
We present a theory for tunneling between a real surface and a model probe tip, applicable to the recently developed "scanning tunneling microscope." The tunneling current is found to be proportional to the local density of states of the surface, at the position of the tip. The effective lateral resolution is related to the tip radius R and the vacuum gap distance d approximately as [(2 A)(R +d...
متن کاملThe Scanning Confocal Electron Microscope
The Scanning Confocal Electron Microscope, is an instrument which permits the observation and characterization of sub-surface structures of thick, optically opaque materials at nanometer level resolutions. The instrument merges the capabilities of the scanning, transmission and x-ray microscopes, and achieves unprecedented resolutions in optically dense materials, by implementing the technology...
