Název v původním jazyce

Potassium-silicate glass foil irradiated with electrons – Asymmetry in migration and space distribution given by the elastic scattering of electrons on potassium atoms

Popis výsledku v původním jazyce

Binary potassium silicate glass 15K2O⋅85SiO2 was prepared in the form of a thin foil and was irradiated with electrons in the transmission mode. A defocused beam of 10, 20, 30, and 50 keV energy was used to prevent a significant temperature increase. Both, the front and back surfaces were depleted of potassium by the irradiation, but not to the same extent the front surface was quickly fully depleted of potassium, but the backside only partially. The potassium depth distribution was not consistent with the assumed shape of the electric field established in the solid, but was significantly shif ted from the middle of the foil. The found asymmetry is due to the momentum transfer from the elastic scattering of the incident electron to the potassium ion, which acts as an additional effective force.
