Notes:
Negative and positive charging of ionic monocrystals (KCl, NaCl, Al2O3, MgO, SiO2 and LiH) under low-energy electron irradiation is investigated by AES and mass spectrometry. Secondary emission and electron-stimulated desorption negative ions of LiH data are presented. The mass spectra of sputtered neutrals post-ionized into negative ions, and their ionization coefficients on the auxiliary target with a low work function, are presented. A phenomenological model of charging of dielectrics that depends on defect formation and secondary emission properties under low-energy electron irradiation is presented.
