Plasmon Dispersion of MXenes
Plasmons in MXenes play a role in electromagnetic absorption, but the effect has never been quantitatively analyzed due to the lack of plasmon dispersion. In article number 2201120, Xiaoxia Yang, Peng Gao, Qing Dai, and co‐workers report the use of high‐spatial‐resolution electron‐energy‐loss spectroscopy to measure the plasmon dispersion of suspended MXenes. These ultrathin...
2D metal carbides and nitrides (MXene) are promising candidates for electromagnetic (EM) shielding, saturable absorption, thermal therapy, and photocatalysis owing to their excellent EM absorption. The plasmon resonances in metallic MXene micro/nanostructures may play an important role in enhancing the EM absorption; however, their contribution has not been determined due to the lack of a precise...
