چکیده	Nowadays, controlling the light reflection and transmission by metasurface nanostructures opens pathways for efficient energy harvesting in nanophotonics and optoelectronic devices. This paper demonstrates a metasurface broadband absorber in the visible wavelength region of 400–800 nm using two-dimensional titanium carbide (Ti3C2Tx) MXene. A high average absorption of 97.85% over a wide wavelength region of the incident light (0.4 µm) is achieved. This significant absorption is due to the strong localized surface plasmon caused by the Ti3C2Tx periodic nanoarrays top-mounted on SiO2/Au/glass layers. The proposed MXene-based absorber also shows broadband and high average absorption for both transverse electric (TE) and transverse magnetic (TM) polarizations under a wide range of oblique incidence and azimuthal light angles, especially it reaches over 99% for TM polarization in some ranges. The proposed absorber can be used in photodetectors, sensors, and applications where the incident angle and/or polarization are constantly changing.
