“…Consequently, chemical vapor deposition has emerged as a scalable and efficient alternative for fabricating large-area porous structures that possess a signicant degree of exibility. 106 To ensure product homogeneity, the metal-organic compound chemical vapor deposition (MOCVD) strategy uses a high-purity metal-organic or compound gas as the precursor for gas-phase epitaxial growth via thermal treatment. It is widely used to prepare low-dimensional materials such as TM compounds because its components and interfaces are highly controllable.…”

“…[ 20–22 ] However, in conventional carbon supply CVD growth, it is not easy to maintain the island shape and produce any‐sized hexagonal graphene islands owing to its environmentally sensitive nature and complex mechanisms involved in the continuous growth process. [ 23–25 ] It is still challenging to achieve the continuously controllable growth of high‐quality hexagonal graphene with varying island sizes.…”

Controlling the morphology of graphene and other two-dimensional (2D) materials in chemical vapor deposition (CVD) growth is crucial because the morphology reflects the crystal quality of as-synthesized nanomaterials in a certain way, and consequently it indirectly represents the physical properties of 2D materials such as band gap, selective ion transportation, and impermeability. However, precise control of the morphology is limited by the complex formation mechanism and sensitive growth-environment factors of graphene. Therefore, the CVD synthesis of single-crystal hexagonal-shaped graphene islands with specific sizes is challenging. Herein, an unconventional nonlinear carbon supply growth strategy is proposed to realize controllable CVD growth of desired hexagonal graphene islands with specific sizes on Cu substrates. Large-area graphene films of isolated islands with desired densities, sizes, and distances between the islands were successfully synthesized. Subsequently, the direct growth of a planar-tunnel-junction structure based on two parallel gapped graphene islands was achieved by specific adjustment of the growth and etching processes of graphene CVD synthesis. We therefore demonstrated that the nonlinear carbon supply growth strategy is a reliable method for the synthesis of high-quality graphene and can facilitate the direct growth of graphene-based nanodevices in the future.

“…By contrast, single‐layer graphene (SLG) can be prepared in a controllable manner with a low level of structural defects using chemical vapor deposition. [ 6 ] Moreover, SLG has larger carrier mobility, higher conductivity, lower light absorption, and better chemical stability compared with its derivatives. [ 7 ] In addition, the pinhole‐free large‐area SLG film can be transferred onto arbitrary substrates and protect semiconductor photoelectrodes from degradation.…”

Single‐layer graphene (SLG) has drawn considerable interest in photoelectrochemical (PEC) cells due to its atomically flat pinhole‐free structure and remarkable in‐plane carrier mobility. It is challenging, however, to obtain efficient SLG‐modified photoelectrodes for PEC water splitting mainly due to the inefficient charge transfer interface. Here, a transition metal oxide/SLG/transition metal sandwich structure modified n‐Si‐based model photoanode is constructed to regulate the interfacial charge transfer behavior for enhanced PEC water oxidation performance. In this sandwich configuration, SLG tailors the morphology, structure, and work function properties of surface metal electrocatalysts to obtain both higher thermodynamic photovoltage and faster kinetical charge transfer at the semiconductor/electrolyte interface. In addition, SLG promotes the surface catalytic reaction as an effective charge trap and storage layer. This study provides a new structural design to engineer the SLG interfacial properties for high‐performance energy conversion devices.
