We have demonstrated the fabrication of both armchair and zigzag epitaxial graphene nanoribbon (GNR) devices on 4H–SiC using a polymer-assisted sublimation growth method. The phenomenon terrace step formation has traditionally introduced risk GNR deformation along sidewalls, but method helps mitigate this risk. Each type 50 nm wide is examined electrically optically (armchair zigzag), with latt...

The permanent is important invariants of a graph with some applications in physics. If G adjacency matrix id="M2"> A = a i j , then the id="M3"> defined as id="M4"> perm open="(...

We report the one-electron spectrum and eigenstates of infinite achiral chiral $(2m,m)$ carbon nanotubes found by using analytic solution to Schr\"odinger equation for tight-binding H\"uckel-type Hamiltonian. With help matching wave functions on interfaces between regions, where electrons have different site energies, we find compare transmission coefficients zigzag, armchair subjected action a...

The interface stability of hybrid silicene/fluorosilicene nanoribbons (SFNRs) has been investigated by using density functional theory calculations, where fluorosilicene is the fully fluorinated silicene. It is found that the diffusion of F atoms at the zigzag and armchair interfaces of SFNRs is endothermic, and the corresponding minimum energy barriers are respectively 1.66 and 1.56 eV, which ...
