چکیده
MXenes are two-dimensional transition-metal carbides and nitrides with an attractive combination of physicochemical properties, gaining notable potential in many applications. Currently, MXene synthesis is mainly performed from powder precursors whose purity grain size define the quality flake 2D sheets, typically not exceeding 2–3 μm. In this work, we successfully synthesize macroscopic nanolayered V2CTz lateral dimensions larger than 25 μm a V2AlC single crystal by exploiting new strategy based on ion implantation. Ne2+ implantation single-crystal precursor applied to introduce defects structure V2AlC, which facilitates chemical etching drastically reduces time down 8 h (∼10 times lower as compared conventional precursors). The morphology exfoliated multilayers have been comprehensively studied performing detailed analyses different kinds microscopies spectroscopies. obtained flakes ideal objects study intrinsic physical properties explore their application, particular, membranes.

Germanium and carbon ions represent a significant portion of total ion implantation steps in the process flow. Very often ion source materials that used to produce ions are chemically aggressive, especially at higher temperatures, and result in fast ion source performance degradation and a very limited lifetime. GeF4 and CO2 are commonly used to generate germanium and carbon beams. In the case ...
