Emission dynamic of ions by monocycle THz pulse
Résumé
We recently proved that high amplitude THz monocycle (20MV/m) is enhanced at the vicinity of the apex of nanometric needle to <1GV/m [1]. The field is in the magnitude range of internal field of solid materials (10-100GV/m). It is able to trigger field emission of atoms from the surface of the nanometric needle [2] and positively ionizes them.
