“…The theoretical bandstructure discussed in the next section will allow further interpretation of these data. The absence of any clear quasiparticle crossing stands in contradiction with the metallic character of the resistivity vs temperature curves [9] and can, as discussed above, not be explained by only taking into account the Peierls scenario. Electron-phonon coupling is expected to be relatively strong for the tellurides [6], consequently polaronic effects may play a role.…”

The origin of the monoclinic distortion and domain formation in the quasi two-dimensional layer compound NbTe2 is investigated. Angle-resolved photoemission shows that the Fermi surface is pseudogapped over large portions of the Brillouin zone. Ab initio calculation of the electron and phonon bandstructure as well as the static RPA susceptibility lead us to conclude that Fermi surface nesting and electron-phonon coupling play a key role in the lowering of the crystal symmetry and in the formation of the charge density wave phase.

“…Previous research has reported that room‐temperature metallic TMD materials occur as 1T‐VS 2 , 1T‐VSe 2 , 1T‐TcS 2 , 2H‐TaSe 2 , 1T‐NbSe 2 , etc. For vanadium dichalcogenides, intralayer vanadium atoms in a single layer ( Figure A,D) form a network structure, causing strong electron–electron interactions and exhibiting metallic behaviors.…”

Recent years have witnessed great developments in inorganic 2D nanomaterials for their unique dimensional confinement and diverse electronic energy bands. Precisely regulating their intrinsic electrical behaviors would bring superior electrical conductivity, rendering 2D nanomaterials ideal candidates for active materials in electrochemical applications when combined with the excellent reaction activity from the inorganic lattice. This Concept focuses on highly conducting inorganic 2D nanomaterials, including intrinsic metallic 2D nanomaterials and artificial highly conductive 2D nanomaterials. The intrinsic metallicity of 2D nanomaterials is derived from their closely packed atomic structures that ensure maximum overlapping of electron orbitals, while artificial highly conductive 2D nanomaterials could be achieved by designed methodologies of surface modification, intralayer ion doping, and lattice strain, in which atomic-scale structural modulation plays a vital role in realizing conducting behaviors. Benefiting from fast electron transfer, high reaction activity, as well as large surface areas arising from the 2D inorganic lattice, highly conducting 2D nanomaterials open up prospects for enhancing performance in electrochemical catalysis and electrochemical capacitors. Conductive 2D inorganic nanomaterials promise higher efficiency for electrochemical applications of energy conversion and storage.

“…After more than a decade of research efforts spurred by graphene, the arena of 2D materials is now populated with superconductors (e.g., NbSe 2 ), metals (e.g., borophene and NbTe 2 ), semimetals (e.g., graphene), semiconductors (e.g., black phosphorus (BP) and MoS 2 ), and insulators (e.g., hexagonal BN (hBN) and Bi 2 Se 3 ). Including graphene, most of the 2D materials are integral parts of bulk layered van der Waals crystals.…”

2D materials and heterostructures have attracted significant attention for a variety of nanoelectronic and optoelectronic applications. At the atomically thin limit, the material characteristics and functionalities are dominated by surface chemistry and interface coupling. Therefore, methods for comprehensively characterizing and precisely controlling surfaces and interfaces are required to realize the full technological potential of 2D materials. Here, the surface and interface properties that govern the performance of 2D materials are introduced. Then the experimental approaches that resolve surface and interface phenomena down to the atomic scale, as well as strategies that allow tuning and optimization of interfacial interactions in van der Waals heterostructures, are systematically reviewed. Finally, a future outlook that delineates the remaining challenges and opportunities for 2D material interface characterization and control is presented.
