| 摘要 | The charge transport of electron-doped Mott insulators on a triangular lattice is investigated within the t-J model. The conductivity spectrum shows a low-energy peak and an unusual midinfrared band, while the resistivity is characterized by a crossover from the high temperature metalliclike behavior to low temperature insulatinglike behavior, in qualitative agreement with experiments. Our results also show that the mechanism that causes this unusual charge transport is closely related to a competition between the kinetic energy and the magnetic energy in the system. |
