Tuning the band structure, magnetic and transport properties of the zigzag graphene nanoribbons/hexagonal boron nitride heterostructures by transverse electric field

Ilyasov, V. V., E-mail: viily@mail.ru, E-mail: chuongnguyen11@gmail.com ; Meshi, B. C. ; Nguyen, V. C., E-mail: viily@mail.ru, E-mail: chuongnguyen11@gmail.com ; ... - Journal of Chemical Physics

The paper presents the results of ab initio study of the opportunities for tuning the band structure, magnetic and transport properties of zigzag graphene nanoribbon (8-ZGNR) on hexagonal boron nitride (h-BN(0001)) semiconductor heterostructure by transverse electric field (E{sub ext}). This study was performed within the framework of the density functional theory (DFT) using Grimme's (DFT-D2) scheme. We established the critical values of E{sub ext} for the 8-ZGNR/h-BN(0001) heterostructure, thereby providing for semiconductor-halfmetal transition in one of electron spin configurations. This study also showed that the degeneration in energy of the localized edge states is removed when E{sub ext} is applied.more »« less

Effect of topology on the critical charge in graphene

Chakraborty, Baishali ; Gupta, Kumar S. ; Sen, Siddhartha - Physical Review. B, Condensed Matter and Materials Physics

We show that the critical charge for the Dirac excitations in gapless graphene depends on the spatial topology of the sample. In particular, for graphene cones, the effective value of the critical charge can tend toward zero for a suitable angle of the conical sample. We discuss the nature of the scattering phase shifts, quasibound state energies, and local density of states for a gapless graphene cone and determine the dependence of these physical quantities on the sample topology.
