Emittance of a field emission electron source
An analytical formula of the emittance of a field emitter is given. In contrast to thermal and photoemission, such a formula contains complexity due to the multidimensional nature of the source. A formulation of emittance is given for oneand three-dimensional 3D field emitters. The 3D formulation makes use of the point charge model of a unit cell emitter coupled with a trajectory analysis to fo...
متن کاملSpectral Interferometry with Electron Microscopes
Interference patterns are not only a defining characteristic of waves, but also have several applications; characterization of coherent processes and holography. Spatial holography with electron waves, has paved the way towards space-resolved characterization of magnetic domains and electrostatic potentials with angstrom spatial resolution. Another impetus in electron microscopy has been introd...
متن کاملInvestigating Bacterial Pathogen-host Interaction by Using Scanning Electron Microscopes and Transmission Electron Microscopes
Electron microscopes have been widely used to investigate cell structures under high resolution. A scanning electron microscope (SEM) provides tridimensional images of a cell surface, while a transmission electron microscope (TEM) is commonly employed to observe the internal structure changes of host cells after bacterial adherence and invasion. The SEM and TEM can reveal bacterial location, bi...
متن کاملIntrinsic instability of aberration-corrected electron microscopes.
Aberration-corrected microscopes with subatomic resolution will impact broad areas of science and technology. However, the experimentally observed lifetime of the corrected state is just a few minutes. Here we show that the corrected state is intrinsically unstable; the higher its quality, the more unstable it is. Analyzing the contrast transfer function near optimum correction, we define an "i...
متن کاملA Need for Bandwidth Limitations in Electron Microscopes
In light-optical microscopes, numerical apertures (apertures in the back focal plane of the objective lens) are an integral part. Often, these apertures can be adjusted continuously, e.g., in single lens reflex (SLR) cameras. In electron microscopy however, and despite much larger magnification ranges, there is only a limited selection of fixed apertures. This is due a) to the pm wave length of...
