The edge-to-edge connected metal-semiconductor junction (MSJ) for two-dimensional (2D) transistors has the potential to reduce contact length while improving performance of devices. However, typical 2D materials are thermally and chemically unstable, which impedes reproducible achievement high-quality edge contacts. Here we present a scalable synthetic strategy fabricate low-resistance contacts atomic using stable metal, PtTe2. use PtTe2 as an epitaxial template enables lateral growth...
The last decade has witnessed significant progress in two-dimensional van der Waals (2D vdW) materials research; however, a number of challenges remain for their practical applications. most challenge 2D vdW is the control early stages nucleation and growth material on preferred surfaces to eventually create large grains with digital thickness controllability, which will enable incorporation into high-performance electronic optoelectronic devices. This Perspective discusses technical be...
The practical application of 2D MXenes in electronic and energy fields has been hindered by the severe variation quality MXene products depending on parent MAX phases, manufacturing techniques, preparation parameters. In particular, their synthesis impeded lack studies reporting high-quality phases. addition, controllable uniform deposition various large-scale substrates is urgently required to use them practically. Herein, a method pelletizing raw materials could synthesize stoichiometric...
Large-scale fabrication of neutron-shielding films with flexible or complex shapes is challenging. Uniform and high boron carbide (B4C) filler loads sufficient workability are needed to achieve good neutron-absorption capacity. Here, we show that a two-dimensional (2D) Ti3C2Tx MXene hybrid film homogeneously distributed B4C particles exhibits mechanical flexibility anomalous properties. Layered solution-processable 2D flakes serve as an ideal robust matrix for high-content fillers (60 wt.%)....
Abstract Broadband and ultrathin electromagnetic interference (EMI)‐shielding materials are crucial for efficient high‐frequency data transmission in emerging technologies. MXenes renowned their outstanding electrical conductivity EMI‐shielding capability. While substituting nitrogen (N) carbon (C) atoms the conventional MXene structure is theoretically expected to enhance these properties, synthesis challenges have hindered progress. Here, it demonstrated that Ti x C y N ‐ ‐1 T z films with...
Abstract Two‐dimensional transition metal carbides and nitrides (MXenes) show great promise for electromagnetic interference (EMI) shielding. However, their susceptibility to oxidation, particularly in humid environments or water, limits industrial applications. This study introduces a straightforward method developing functionalized MXenes (F‐MXenes) with significantly enhanced oxidation resistance environmental stability, which are critical factors scalability. The resulting F‐MXenes...
Abstract As the elements of integrated circuits are downsized to nanoscale, current Cu‐based interconnects facing limitations due increased resistivity and decreased current‐carrying capacity because scaling. Here, bottom‐up synthesis single‐crystalline WTe 2 nanobelts low‐ high‐field electrical characterization nanoscale interconnect test structures in various ambient conditions reported. Unlike exfoliated flakes obtained by top‐down approach, growth mode allows systemic properties single...
