30 An electron is in an electric field of st ength5*10^4vm^(-1) . The field is the only influence on the electron.The mass and charge of an electron are known.Which quantity can be calculated without any more information? A A the force on the electron B the momentum of the elec...
The Schroedinger equation for an electron in a time-dependent electric field and a static magnetic field is solved by introducing a unitary transformation that eliminates the time-dependent electric field. The effect of impurities is als... M Fujita - 《Proceedings of the School of Science of To...
Triple point, defined as the junction of metal, dielectric, and vacuum, is the location where electron emission is favored in the presence of a sufficiently strong electric field. In addition to being an electron source, the triple point is generally regarded as the location where flashover is ...
Electron energies and the strength of electric fields in sprites are deduced for five selected events, which were recorded by the space-borne instrument called ISUAL (Imager of Sprites and Upper Atmospheric Lightning; a payload on the FORMOSAT-2 satellite). From the derived peak intensity ratios ...
Influence of electric field on electron emission from DX(Te) centres in Al0.55Ga0.45As The authors show that the electric field strongly influences the electron emission from the effective-mass, metastable, excited states of DX centres in Al0... L,Dobaczewski,J,... - 《Semiconductor Science ...
MAGNETIC FIELD SUPERIMPOSING TYPE SUPERCONDUCTIVE ELECTRIC FIELD RADIATING ELECTRON GUN PURPOSE:To make it possible to pick up stably electric field emission electron beams with low aberration and high luminance by getting magnetic flux trapped in positive electrodes made of a superconductor to make it ...
An electron is released from rest in a uniform electric field with a magnitude of \(5.0*10^{2} V/m\). What is the speed of the electron in \(m/s\) after being displaced a distance \(d = 0.8\,m\) in the opposite direction of \(\vec{E}\)?___ 相关知识点: 试题来源: 解...
Electric-dipole-induced spin resonance in quantum dots An alternating electric field, applied to a quantum dot, couples to the electron spin via the spin-orbit interaction. We analyze different types of spin-or... Vitaly,N.,Golovach,... - 《Physical Review B》 被引量: 53发表: 2006年 ESR...

The effect of electron drift on the transverse size of the spark channels in a multichannel sliding discharge on a dielectric surface is considered in a semianalytic approximation. The strength of an electric field transverse to the channel axis is estimated by the mirror image method. The estimate...
