Lattice kirigami, ultralight metamaterials, polydisperse aggregates, ceramic nanolattices, and 2D atomic materials share an inherent structural discreteness, and their material properties evolve with their shape. To exemplify the intimate relation among material properties and the local geometry, we explore the properties of phosphorene--a new 2D atomic material--in a conical structure, and doc...

Black phosphorous (BP) is is recently unveiled as a promising two-dimensional direct bandgap semiconducting material. Here, we report the ambipolar field effect transistor behavior of multilayers of BP with ferromagnetic tunnel contacts. We observe a reduced of Schottky barrier < 50 meV by using TiO2/Co contacts, which could be further tuned by gate voltages. Eminently a good transistor perform...

We theoretically study emergent edge and corner states in monolayer blue phosphorus (blue phosphorene) using the first-principles calculation tight-binding model. show that existence of Wannier orbitals at every bond center yields both zigzag armchair nanoribbons. The properties can be well described by a simple effective Hamiltonian for uncoupled orbitals, where structural relaxation near boun...

The magnetic ratchet effect has been studied in phosphorene by the use of Boltzmann kinetic equation that is a semi-classical approach. Hamiltonian steady parallel field derived using tight-binding model. We consider on non--linear dynamics presence an ac laser and spatial inversion asymmetry. have shown for anisotropic 2D materials phosphorene, current response to three different light polariz...

Abstract Phosphorene, a single layer of black phosphorus, is attracting interest for several applications, among which tribology. Here, we investigate its possible use as solid lubricant iron-based materials by comparing friction-reduction properties with $$\hbox {MoS}_{2}$$ MoS 2 </mml:...

If graphene had a band gap, it would probably be the optimum 2D system for electronics applications. Layered transition metal dichalcogenides (TMDs) with a robust intrinsic band gap appear as the nextbest alternative. Only after a long search, however, optimum strategies have been devised to make lowresistance, ohmic contacts to TMDs [1]. In the meantime, a new class of 2D semiconductors has be...
