electron emission उदाहरण वाक्य

उदाहरण वाक्य

1. However the electron spin is 1 / 2, so that angular momentum would not be conserved if beta decay were simply electron emission.
2. The massive short pulse of high voltage causes the cathode to emit an intense burst of electrons by the field electron emission mechanism.
3. It can be seen in the below chart what a typical I-V curve looks like for a hollow cathode in electron emission mode.
4. In addition to using a ribbed beam screen designed to minimize secondary electron emission, the effect can also be reduced by in-situ electron bombardment.
5. Owing to the large number of highly curved fullerene surfaces acting as electron emission sites on conductive carbon nanotubes, nanobuds possess advantageous field electron emission characteristics.
6. Owing to the large number of highly curved fullerene surfaces acting as electron emission sites on conductive carbon nanotubes, nanobuds possess advantageous field electron emission characteristics.
7. As noted at the beginning, the effects of the atomic structure of materials are disregarded in the relatively simple treatments of field electron emission discussed here.
8. Secondary electron emission is used in photomultiplier tubes and image intensifier tubes to amplify the small number of photoelectrons produced by photoemission, making the tube more sensitive.
9. Once the tube strikes, the impinging main discharge keeps the cathodes hot, permitting continued electron emission without the need for the filaments to continue to be heated.
10. Phototubes and photomultipliers rely on electron flow through a vacuum, though in those cases electron emission from the cathode depends on energy from photons rather than thermionic emission.
