“…CuNi alloy is demonstrated to be one of the best substrates for the growth of graphene because the very fast growth rate and low nucleation density can be simultaneously achieved. 10,15,48,77 As is shown in Figure 3D,E, from the growth of 1.5-in. single-crystal graphene from a single nucleus, we can observe that the nucleation density decreases monotonically when the Ni composition in the CuNi alloy increases from 0% to 30%.…”

“…Their practical applications in high‐performance electronics and optoelectronics, such as touch screen, radio frequency devices, photovoltaic devices, solar cell, and so on, are hampered by their poor crystalline quality and limited size. Wafer‐scale and high‐quality 2D materials with few or even without grain boundaries will exhibit excellent electronic performance with high charge mobility, and low interface scattering, which is beneficial in modern electronics . Therefore, routes toward the synthesis of high‐quality (especially single‐crystal) wafer‐scale 2D materials that are compatible with current semiconductor microfabrication processes are essential for exploring the full potential of them in the practical applications.…”

Emerging two‐dimensional (2D) materials have stimulated tremendous scientific and industrial interests due to their diverse and tunable physical, chemical, and mechanical properties. The scalable production of high‐quality wafer‐scale 2D materials has become significantly essential to bring us closer to practical industrial applications, particularly in electronic devices. Vapor‐phase growth provides attractive opportunities for the synthesis of large‐area and high‐quality 2D materials. In this review, we will emphasize vapor‐phase growth strategies from three aspects, including suppressing nucleation, seamless stitching, and evolutionary selection growth. We discuss the general understanding of the related fundamental mechanism and specific parameter optimization from precursors and substrate design to the adjusting of growth parameters (temperature and pressure). Meanwhile, we present other strategies to produce various kinds of wafer‐scale 2D materials. Finally, we conclude the current challenges and future directions in this developing field. This work may inspire researchers to better design routes in the synthesis of wafer‐scale 2D materials with high quality.

“…The challenge in the synthesis of large‐area 2D layered materials also limits their practical applications in neuromorphic computing. Although major progresses in large‐area synthesis of monolayer 2D materials such as graphene, TMDs, and h‐BN have been achieved, it remains challenging to grow large‐area 2D layered materials with controlled thickness. Recently, a few interesting device concepts have been proposed, but their promising applications are also limited due to the lack of transformative technology in the fabrication of large‐area vdW heterostructures.…”

demonstrated that the memristive devices exhibit many promising features, [3][4][5][6][7][8] such as non-volatility, high speed switching, high endurance, high-density integration, CMOS-compatible fabrication, and so on. These features make them ideal candidates for applications in memory devices, [3,5,9] in-memory computing, [3,[10][11][12] and edge computing. [13,14] The working principle of the TMOs-based memristive devices relies on ion drift or diffusion, which resembles motion of ions in the biological neurons and synapses. The ionic motions exhibit dynamic behaviors. Thus, the memristive devices can be used to emulate the synaptic plasticity [15] and neurons. [16][17][18] Compared to traditional silicon synapses [19][20][21] and neurons [22,23] requiring complex circuits, such emerging memristive devices have compact structures and enhanced func-

2D materials and the associated heterostructures define an ideal material platform for investigating physical and chemical properties, and exhibiting new functional applications in (opto)electronic devices, electrocatalysis, and energy storage. 2D transition metal dichalcogenides (2D TMDs), as a member of the 2D materials family including 2D semiconducting TMDs (s-TMDs) and 2D metallic/semimetallic TMDs (m-TMDs) have attracted considerable attention in the scientific community. Over the past decade, the 2D s-TMDs have been extensively researched and reviewed elsewhere. Because of their distinctive physical properties including intrinsic magnetism, chargedensity-wave order and superconductivity, and potential applications, such as high-performance electronic devices, catalysis, and as metal electrode contacts, 2D m-TMDs have grabbed widespread attention in recent years. However, reviews demonstrating the m-TMDs systematically and comprehensively have been rarely reported. Here, the recent advances in 2D m-TMDs in the aspects of their unique structures, synthetic approaches, distinctive physical properties, and functional applications are highlighted. Finally, the current challenges and perspectives are discussed.
