TL;DR: A novel approach to tuning the anion-dependent electrocatalytic characteristics in MTM-based catalyst for HER, using holey Ni/Co-based phosphides/selenides/oxides (Ni-Co-A, A = P, Se, O) as the model materials, and electrochemical results reveal that P substitution could modulate the electron configuration, lower the hydrogen adsorption energy, and facilitate the desorption of hydrogen on the active sites in Ni-

TL;DR: The first black-phosphorus synaptic device is demonstrated, which offers intrinsic anisotropy in its synaptic characteristics directly resulting from its low crystalline symmetry, which represents an important step toward introducing intrinsic heterogeneity to artificial neuromorphic systems.

TL;DR: The unique thickness-dependent bandgap tuning properties in intrinsic black phosphorus, arising from the strong interlayer electronic-state coupling, are revealed and may pave the way for the investigation of electrically tunable topological insulators and semimetals.

TL;DR: A one-step synthesis procedure for large-area vdW heterostructures between horizontal TMDCs MoS2 and WS2 is demonstrated, which indicates that, in addition to the catalytically active sulfur edge sites, defect sites may serve as catalyst sites.

TL;DR: An artificial synaptic device concept, an ambipolar junction synaptic devices, which utilizes the tunable electronic properties of the heterojunction between two layered semiconductor materials black phosphorus and tin selenide to mimic the different states of the synaptic connection and realize the dynamic reconfigurability between excitatory and inhibitory postsynaptic effects.
