| Popis: | A suppression of tunnelling ionization of deep impurities in terahertz frequency electric fields by a magnetic field is observed. It is shown that the ionization probability at external magnetic field, B , oriented perpendicular to the electric field of terahertz radiation, E , is substantially smaller than that at B || E . The effect occurs at low temperatures and high magnetic fields. |
