dc.description | In this work, we study the effects of an external magnetic field on the charge and current density in finite monolayer graphene, i.e., with zig-zag and armchair edges. We use the tight-binding model to include the effects of the magnetic field and the effect of the edges. By using the transmisión probability and analyzing the local density of states (charge density) obtained from Green’s function method, we find an energy region where the wave functions are more localized in the edges and, consequently, the current flow across the borders. On the other hand, for energies close to Landau levels, the charge and current density are localized on the bulk of the system. | eng |
dc.description | En este trabajo, estudiamos los efectos de un campo magnético externo sobre la densidad de carga y la densidad de corriente de una monocapa de grafeno finita, es decir, con bordes zig-zag y armchair. Usamos el modelo tight-binding para incluir los efectos del campo magnético y el efecto de los bordes. Utilizando la probabilidad de transmisión y analizando la densidad local de estados (densidad de carga), obtenidas por el método recursivo de las funciones de Green, encontramos que hay regiones de energía donde las funciones de onda están más localizadas en los bordes y, en consecuencia, la corriente fluye a través de estos. Por otro lado, para energías cercanas a los niveles de Landau, la carga y la corriente se localizan en mayor parte en el centro del sistema. | spa |
