这一篇介绍一些 二维范德瓦尔斯 （van der Waals，简写为vdW）异质结的制备法，主要介绍通过人工堆叠的方式制备得到存在耦合的二维vdW异质结，相关的其他内容也讲了一些。

2025年1月16日 · In this study, we develop a highly efficient and versatile sequential pick-up method for assembling CVD-synthesized 2D materials into vdW structures using a plasma-treated PVC film (P-PVC). Plasma treatment can be used to generate a sacrificial layer composed of PVC with a low molecular weight and hydrophilic surface.

2024年11月18日 · Chemical vapor deposition (CVD) is a widely used technique for preparing large-area and high-quality TMDCs. Yet, it suffers from the challenge of transfer due to the strong interaction between 2D materials and substrates. The traditional PMMA-assisted wet etching method tends to induce damage, wrinkles, and inevitable polymer residues.

2024年8月21日 · Here, we combine CVD-grown 2D semiconductor MoS 2 and graphene in vdW heterostructure that offers the possibility to create devices with various functionalities. We demonstrate all-2D MoS 2 FET...

2024年6月1日 · The construction of vertical van der Waals (vdW) heterostructures (HSs) via stacking various two-dimensional (2D) crystals, including semiconducting transition metal dichalcogenides (TMDCs), has accelerated the perspective development of electronics, optoelectronics and energy devices owing to their unprecedented physical and chemical features ...

2024年5月28日 · This paper presents an efficient and adaptable method for assembling van der Waals (vdW) heterostructures from CVD-grown 2D materials. The plasma-modified PVC (P-PVC) film enabled an efficient sequential pick-up, which …

6 天之前 · For the growth of ReS 2, a space-confined CVD setup was constructed with sodium perrhenate (NaReO 4, 99.95%, RHAWN) and sulfur (S, 99.5%, Sigma-Aldrich, 200 mg) used as precursors. 0.01 mol/L ...

2025年3月13日 · Controlled growth through chemical vapor deposition (CVD) (9 ... forming a crystalline structure. The van der Waals (vdW) interactions between SWNTs within this structure help drive the alignment and produce the uniform intertube spacing. Molecular dynamics (MD) simulations revealed that the growth proceeds through self-assembly facilitated by ...

2025年3月21日 · For example, the CVD growth of 2D material involves exothermic reactions where enthalpy changes ensure the synthesis of defect-free layers. In vdW heterostructures, interlayer interactions, stability, and layer alignment depend on enthalpic contributions. Thermal management in smart devices also depends on enthalpy.

通过堆叠各种二维 （2d） 过渡金属硫化物 （tmdc） 晶体构建垂直范德华 （vdw） 异质结构 （hs），为通过转移方法改变相对物理特性提供了另一种途径。然而，通过一步化学气相沉积 （cvd） 制造 2d 多层 tmdc vdw hs 仍然具有挑战性。
