Control of light transmission and reflection through nanostructured materials has led to demonstration of metamaterial absorbers that have augmented the performance of energy harvesting applications of several optoelectronic and nanophotonic systems. Here, for the first time, a broadband plasmonic metamaterial absorber is fabricated using two-dimensional titanium carbide (Ti₃C₂T_x) MXene. Arrays of nanodisks made of Ti₃C₂T_x exhibit strong localized surface plasmon resonances at near-infrared frequencies. By exploiting the scattering enhancement at the resonances and the optical losses inherent to Ti₃C₂T_x MXene, high-efficiency absorption (∼90%) for a wide wavelength window of incident illumination (∼1.55 μm) has been achieved.

使用等离子碳化钛（MXene）的高宽带吸收器

通过纳米结构材料的光传输和反射的控制已导致超材料吸收器的演示，这些吸收器增强了几种光电和纳米光子系统的能量收集应用程序的性能。在这里，首次使用二维碳化钛（Ti ₃ C ₂ T _x）MXene制造宽带等离子超材料吸收体。由Ti ₃ C ₂ T _x制成的纳米盘阵列在近红外频率下表现出很强的局部表面等离振子共振。通过利用共振处的散射增强和Ti ₃ C ₂ T _x固有的光学损耗 MXene已实现了对入射照明的宽波长窗口（约1.55μm）的高效吸收（约90％）。
