      abstract     = {We introduce a solution for producing ultrashort (∼fs)
                      high charge (∼pC) from ultracompact guns utilizing
                      single-cycle THz pulses. We show that the readily available
                      THz pulses with energies as low as 20  $\mu$J are
                      sufficient to generate multi-10 keV electron bunches.
                      Moreover, it is demonstrated that THz energies of 2 mJ are
                      sufficient to generate relativistic electron bunches with
                      higher than 2 MeV energy. The high acceleration gradients
                      possible in the structures provide 30 fs electron bunches at
                      30 keV energy and 45 fs bunches at 2 MeV energy. These
                      structures will underpin future devices for strong field THz
                      physics in general and miniaturized electron guns, in which
                      the high fields combined with the short pulse duration
                      enable electron beams with ultrahigh brightness.},
