Localized surface plasmon resonances in a hybrid structure consisting of a mono-layered Al sheet and Ti₃C₂F MXene

Abstract

Coupling of a mono-layered Al sheet on top of Ti3C2F MXene causes interlayer charge transfer accompanied by strong signatures of localized surface plasmon resonances.

Recent Advances in Real-Time Time-Dependent Density Functional Theory Simulations of Plasmonic Nanostructures and Plasmonic Photocatalysis

“…In this area, MXenes have been investigated, specifically a monolayered Al sheet on top of a Ti 3 C 2 F MXene. 46 Both the Al sheet and the Ti 3 C 2 F MXene showed significantly reduced absorption when the field was oriented normal to the surfaces and the plasmonic features largely disappeared. The disappearance of plasmonic behavior in the z direction was likely due to quantum confinement effects.…”

“…While quasi-one-dimensional and three-dimensional structures represent the bulk of the work done to date, two-dimensional materials are an interesting next application of RT-TDDFT methods. In this area, MXenes have been investigated, specifically a monolayered Al sheet on top of a Ti 3 C 2 F MXene . Both the Al sheet and the Ti 3 C 2 F MXene showed significantly reduced absorption when the field was oriented normal to the surfaces and the plasmonic features largely disappeared.…”

Photo-response of water intercalated Ti3C2O2 MXene

“…Because of their superior metallic properties compared to typical conductors like noble metals, they are extremely desirable for optical and plasmonic applications. [59][60][61][62] It is important to note that a number of optical signatures have recently been reported in MXenes. For instance, El-Demellawi and colleagues examined the effects of altering the surface terminations of Ti 3 C 2 T x by thermally desorbing F functional groups.…”

Optical properties of in-plane chemically ordered i-MAX structures

“…Since 2011, the atomically layered ternary transition metal carbides and/or nitrides known as MAX phases have attracted more attention from the scientific community because they serve as a precursor for their 2D derivatives, the family of socalled MXenes. [1][2][3][4][5][6][7][8][9] MAX phases display a hexagonal crystal structure and are described by the general formula M n+1 AX n , where M stands for an early transition metal (such as Ti, Mo, V, Nb), A denotes mostly a group 13 to 16 element (such as Al, Ga, In, Ge, Sn, Pb, P, or As), and X denotes carbon and/or nitrogen and n is a number between 1 and 4. [10][11][12][13][14][15][16] Due to their thermodynamically stable nanolaminated layered structure, strong covalent M-X interactions, and comparatively weak metallic M-A bonds, MAX phases combine some of the best attributes of metals and ceramics.…”
