Ultrahigh Vacuum Electron Microscope
Review of Scientific Instruments, 1968A Hitachi HU-11B electron microscope has been modified for ultrahigh vacuum operation. Differential sputter ion pumps are used to evacuate the entire microscope column, which was extensively modified to be compatible with the high vacuum, low contamination environment.

Review of Scientific Instruments, 1955
A vacuum dilatometer based on the use of a linear variable differential transformer has been constructed. Expansion or contraction of the specimen moves a silica pusher-rod which, in turn, changes the position of the core of the linear transformer. The output of the transformer is directly proportional to the displacement of this core.

The exploitation of the spectrum beyond 100 GHz is the solution for the full implementation of 5G and the development of 6G concepts. Low-power electronics is already available, but technology advancements are needed to overcome the increasing atmosphere and rain attenuation above 100 GHz, which presently limit the transmission distance.

Vacuum electron-based photodiode
2016 IEEE International Vacuum Electronics Conference (IVEC), 2016We have presented a detailed investigation of hybrid photodiode based on the combination of Gr/Si heterojunction and nanoscale vacuum device based on graphene-SiO2-Si (GrOS) field effect structure. We elucidate on the underlying mechanism of impact-ionization process in a two-Dimensional Electron Gas (2DEG) confined in quantum well, resulting in ...

Electronic Vacuum Technologies
2003Electronic vacuum technology (ET) is an engineering field in which material processing is based on the flow of high-energy particles (e.g., electrons, ions, atoms, and molecules). ET is also known as “electron-ion- plasma technologies” and “elion technologies.” Many ET processes are used to create nontraditional machines, the most important of which is

1994
From its invention in 1906 until about 1950 the vacuum tube has been the key element of electronics. Then it started to be replaced by semiconductor devices. From our everyday experience with consumer electronics we are inclined to conclude that the days of the vacuum tube are over. Nothing is less true, however.

Quasielastic Electron Scattering and Vacuum Polarization
Physical Review Letters, 1989The longitudinal response function for quasielastic electron scattering from /sup 12/C and /sup 40/Ca at a momentum transfer q = 550 MeV is calculated in a relativistic random-phase approximation (RPA). The particle-hole response is calculated exactly in the finite system while vacuum-polarization effects are included in a local-density approximation ...
