  • Abstract
    We have performed terahertz time-domain spectroscopy (THz-TDS) of carrier-doped nanoporous crystal 12CaO·7Al2O3 (C12A7) showing the Mott variable range hopping at room temperature. The frequency dependence of both the real and imaginary parts of the dielectric constant can be simply explained by considering two contributions: a phonon vibration and an AC hopping conduction with the Jonscher law generally reported up to GHz range.
