Directional Control of Charge and Valley Currents in a Graphene-Based Device

Autor: Matias Berdakin, José Eduardo Barrios Vargas, Luis E. F. Foa Torres

We propose a directional switching effect in a metallic device. To such end we exploit a graphene-based device with a three-terminal geometry in the presence of a magnetic field. We show that unidirectional charge and valley currents can be controlle

Charge and Spin Transport in Disordered Graphene-Based Materials

Autor: Dinh Van Tuan

This thesis presents an in-depth theoretical analysis of charge and spin transport properties in complex forms of disordered graphene. It relies on innovative real space computational methods of the time-dependent spreading of electronic wave packets
