“…The two distinctive peaks located at 190.45 eV and 398.4 eV correspond to B 1s and N 1s, respectively. 5,26,27 We assume that the B/N ratio in high-quality h-BN is 1 : 1, and the B/N ratio in C-h-BN is calculated to be 0.96 : 1. This indicates that the C-h-BN sample has a higher density of B vacancies than high-quality h-BN.…”

“…Plasma is usually generated by the radiofrequency between two electrodes. PECVD has developed a reputation for its low-temperature ambient conditions, transfer-free process, and industrial compatibility, which enables the scalable and low-cost preparation of 2D materials [82][83][84][85][86][87]. Moreover, artificial neuron networks can be used in a CVD process to identify and characterize 2D vdWH, ameliorating the efficiency of identifying sample quality and optimizing synthesis parameters [88].…”

With paramount electrical, optical, catalytic, and other physical and chemical properties, van der Waals heterostructures (vdWHs) have captured increasing attention. vdWHs are two-dimension (2D) heterostructures formed via van der Waals (vdW) force, paving the way for fabricating, understanding, and applications of 2D materials. vdWHs materials of large lattice constant difference can be fabricated together, forming a series of unique 2D materials that cannot form heterostructures earlier. Additionally, vdWHs provide a new platform to study the interlayer interactions between materials, unraveling new physics in the system. Notably, vdWHs embody short-range bonds weaker than covalent and ionic bonds, almost only interactions between nearest particles are considered. Owing to a clear interface, vdW interaction between two different components, devices made by vdWHs can bring amazing physicochemical properties, such as unconventional superconductivity, super capacitance in intercalation 2D structure, etc. Recently, impressive progress has been achieved in the controlled preparation of vdWHs and various applications, which will be summarized in this review. The preparation methods comprise mechanical exfoliation, liquid phase stripping, physical vapor deposition, chemical vapor deposition, and metalorganic chemical vapor deposition. The applications sections will focus on photoelectric devices, logic devices, flexible devices, and piezotronics. Finally, some perspectives in the future on the controlled preparation of vdWHs with desired properties for advanced applications will be discussed.
