A design for a subminiature, low energy scanning electron microscope with atomic resolution [PDF]

, 2009
We describe a type of scanning electron microscope that works by directly imaging the electron field-emission sites on a nanotip. Electrons are extracted from the nanotip through a nanoscale aperture, accelerated in a high electric field, and focused to ...

Physical Limits on Atomic Resolution

Microscopy and Microanalysis, 2004
It is shown that the ultimate resolution is not limited by the bandwidth of the microscope but by the bandwidth (i.e., the scattering power) of the object. In the case of a crystal oriented along a zone axis, the scattering is enhanced by the channeling of the electrons.
