Centered Honeycomb NiSe2 Nanoribbons: Structure and Electronic Properties

Electronic structure and magnetic properties of penta-graphene nanoribbons.

2D penta-graphene sheets were cut along typical crystallographic orientations in order to construct various penta-graphene nanoribbon (P-GNR) models, and their electronic structures and magnetic properties were systemically investigated. It was demonstrated that P-GNRs are very versatile with rich and unique electronic and magnetic properties. In particular, bipolar magnetic semiconducting feat...

Graphene Nanoribbons: Geometric, Electronic, and Magnetic Properties

Graphene nanoribbons (GNRs) have one-dimensional structures with hexagonal twodimensional carbon lattices, which are stripes of graphene. Their structures and their electronic and magnetic properties have been intensively studied both experimentally and theoretically. Due to their various edge structures, GNRs present different electronic properties ranging from normal semiconductors to spin-po...

Electronic transport properties of graphene nanoribbons

We will present brief overview on the electronic and transport properties of graphene nanoribbons focusing on the effect of edge shapes and impurity scattering. The low-energy electronic states of graphene have two non-equivalent massless Dirac spectrum. The relative distance between these two Dirac points in the momentum space and edge states due to the existence of the zigzag type graphene ed...

Electronic properties of twisted bilayer nanoribbons

We study the band structure, density of states, and spatial localization of edge states in twisted bilayer graphene nanoribbons. We devise these ribbons by cutting a stripe of commensurate twisted bilayer graphene along a direction with a maximum number of zigzag edge atoms. Due to the spatially inhomogeneous interlayer coupling, edge states stemming from regions with AB stacking are closer to ...
