The design, construction, and testing of a new electron source is described. This source incorporates an electrostatic analyzer for velocity selection on the electron beam before scattering.nThe design, construction, and testing are described in this report and several electron impact spectra are ...
An electron absorption spectrometer with an improved velocity analyzer using the principle of individually designed stages for deceleration, dispersion, and reacceleration is described. The instrument is usable over an energy range of 1 to 50 kev and can obtain angular distribution data over a range ...
1.50\times105m/s enters a region1.0cm long where it is electrically accelerated(see the figure).It emerges with v=5.10\times106m/s.What is its acceleration, assumed constant?(Such a process occurs in the electron gun in...

The resolution of an electron microscope is governed by errors of the magnetic lenses, in particular by the spherical aberration of the objective lens. The ultimate resolution rmin can be reached for an optimum objective aperture angleαopt, with (1)αopt=Aλ1/4Cs−1/4rmin=Bλ3/4Cs1/...
Contact of CNTs and CNT fibers with metal electrodes, as shown in Fig. 10.11(a), has long been reported as Schottky barriers between CNTs and the metal electrodes, which may affect the electron transport. Furthermore, the physical properties of CNTs are much different than those of bulk ...

For example, new versions of fractional Schrödinger equations can be constructed from path integral based on the notions of fractional velocity and the concept of fractional action-like variational approach motivated from fractal arguments (e.g., [171]). However, it is not clear if the ...
