摘要：

Excellent and wide-band absorption is of great benefit for lots of applications such as photoelectric conversions, photonics commutations as well as photovoltaic cells. Here, a simple MXene/Au-based metamaterial, consisting of a thick layer of Ti3C2Tx and Au-Nanorod, is studied through finite-difference time-domain (FDTD) method for realization of tunable strong absorption in the visible and near infrared. The results show that the enhanced wide-band absorption with AMAX = 0.99 can be realized for the proposed MXene/Au-based metamaterial. Moreover, the absorption can be effectively tuned by the structural parameters and polarization. These results may play an important role for designing plasmonic absorbers.
