“…In order to figure out the active sites, a combination of surface sensitive methods and reactivity studies must be sophisticatedly designed 36. Fresh and clean MoS 2 polygonal single layer sheets with different sizes and area coverages could be obtained by a physical vapor deposition and followed by annealing 37. After characterizing by scanning tunneling microscopy (STM) under ultrahigh vacuum chamber ( Figure 1 a) to get structure information, the products was tested for HER activity respectively.…”

Edges are special sites in nanomaterials. The atoms residing on the edges have different environments compared to those in other parts of a nanomaterial and, therefore, they may have different properties. Here, recent progress in nanomaterial fields is summarized from the viewpoint of the edges. Typically, edge sites in MoS2 or metals, other than surface atoms, can perform as active centers for catalytic reactions, so the method to enhance performance lies in the optimization of the edge structures. The edges of multicomponent interfaces present even more possibilities to enhance the activities of nanomaterials. Nanoframes and ultrathin nanowires have similarities to conventional edges of nanoparticles, the application of which as catalysts can help to reduce the use of costly materials. Looking beyond this, the edge structures of graphene are also essential for their properties. In short, the edge structure can influence many properties of materials.

“…The single layer MX 2 has 3-fold rotational symmetry since M and X atoms occupy alternating hexagonal corners at different height. The growth process therefore naturally favors triangular domains as is clearly shown in CVD grown samples and nanoparticles of MX 2 [43,44]. Our MBE grown samples are bound to have a mixture of the domains with triangle point up (uptriangle domain) and its mirror twin domain pointing downwards (down-triangle domain), since they are energetically degenerate.…”

Abstract. MoSe 2 and WSe 2 with a few layer thickness possess non-trivial spin texture with sizable spin splitting due to the inversion symmetry breaking embedded in the crystal structure and strong spin-orbit coupling. We report spinresolved photoemission study of the MoSe 2 and WSe 2 thin film samples epitaxially grown on bilayer graphene substrate. We found spin polarization only in singleand tri-layer samples, but not in bi-layer sample, mostly along the out-of-plane direction of the sample surface. The measured spin polarization is found to be strongly dependent on the light polarization as well as the measurement geometry, which reveals intricate coupling between spin and orbital degrees of freedom in this material class.

Abstract. A highly unconventional superconducting state with a spin-singlet d x 2 −y 2 ± id xy -wave, or chiral d-wave, symmetry has recently been proposed to emerge from electron-electron interactions in doped graphene. Especially graphene doped to the van Hove singularity at 1/4 doping, where the density of states diverges, has been argued to likely be a chiral d-wave superconductor. In this review we summarize the currently mounting theoretical evidence for the existence of a chiral d-wave superconducting state in graphene, obtained with methods ranging from mean-field studies of effective Hamiltonians to angle-resolved renormalization group calculations. We further discuss multiple distinctive properties of the chiral d-wave superconducting state in graphene, as well as its stability in the presence of disorder. We also review means of enhancing the chiral d-wave state using proximity-induced superconductivity. The appearance of chiral d-wave superconductivity is intimately linked to the hexagonal crystal lattice and we also offer a brief overview of other materials which have also been proposed to be chiral d-wave superconductors.
