“…The plasmonic properties of MXenes remain largely unexplored, but limited work on the subject exists. [12][13][14][15][16][17][18][19][20] Mauchamp et al revealed that Ti 3 C 2 T x (T x denotes surface-terminated moieties such as -O or -F) is a plasmonic material; 16 a comprehensive study of the surface plasmons on the material has been performed at infrared (IR) wavelengths. 13 The applications of MXene nanostructures have been investigated as a broadband absorber.…”

“…So far, two research articles [16,24] report the relative dielectric permittivity through experimentation of MXene films. Although none of the research articles provide an analytical expression for the complex permittivity in the terahertz range [4]. This step is very crucial in the simulation of such 2D materials because the performance of the metamaterial depends on the material properties such as dielectric permittivity, refractive index, and conductivity.…”

“…The most common technology for terahertz absorbers are metamaterials, also known as artificially engineered magnetic conductors. Metamaterials are highly conductive and of particular shaped subwavelength periodic structures [4]. Metamaterials achieve absorption at a specific terahertz frequency utilizing intrinsic loss with the aid of complex geometrical design and their control over dielectric permittivity [5] and conductivity properties [6].…”

With the advancement of technology, shielding for terahertz (THz) electronic and communication equipment is increasingly important. The metamaterial absorption technique is mostly used to shield electromagnetic interference (EMI) in THz sensing technologies. The most widely used THz metamaterial absorbers suffer from their narrowband properties and the involvement of complex fabrication techniques. Materials with multifunctional properties, such as adjustable conductivity, broad bandwidth, high flexibility, and robustness, are driving future development to meet THz shielding applications. In this article, a theoretical simulation approach based on finite difference time domain (FDTD) is utilized to study the absorption and shielding characteristics of a two-dimensional (2D) MXene Ti 3 C 2 T x metasurface absorber in the THz band. The proposed metamaterial structure is made up of a square-shaped array of MXene that is 50 nm thick and is placed on top of a silicon substrate. The bottom surface of the silicon is metalized with gold to reduce the transmission and ultimately enhance the absorption at 1-3 THz. The symmetric adjacent space between the MXene array results in a widening of bandwidth. The proposed metasurface achieves 96% absorption under normal illumination of the incident source and acquires an average of 25 dB shielding at 1 THz bandwidth, with the peak shielding reaching 65 dB. The results show that 2D MXene-based stacked metasurfaces can be proven in the realization of low-cost devices for THz shielding and sensing applications.

“…They can be described as electrically conductive clays. There is a large number of 2D materials that belong to MXenes, with a wide range of different properties, with the most frequently encountered one among them being titanium carbide [77]. Other 2D compound materials include gallium arsenide, transition-metal dichalcogenides, sulfides, selenides and tellurides of tungsten, niobium, molybdenum or tantalum, aluminum carbide, cadmium selenide, and many more.…”

Nanomembranes are the principal building block of basically all living organisms, and without them life as we know it would not be possible. Yet in spite of their ubiquity, for a long time their artificial counterparts have mostly been overlooked in mainstream microsystem and nanosystem technologies, being a niche topic at best, instead of holding their rightful position as one of the basic structures in such systems. Synthetic biomimetic nanomembranes are essential in a vast number of seemingly disparate fields, including separation science and technology, sensing technology, environmental protection, renewable energy, process industry, life sciences and biomedicine. In this study, we review the possibilities for the synthesis of inorganic, organic and hybrid nanomembranes mimicking and in some way surpassing living structures, consider their main properties of interest, give a short overview of possible pathways for their enhancement through multifunctionalization, and summarize some of their numerous applications reported to date, with a focus on recent findings. It is our aim to stress the role of functionalized synthetic biomimetic nanomembranes within the context of modern nanoscience and nanotechnologies. We hope to highlight the importance of the topic, as well as to stress its great applicability potentials in many facets of human life.
