Description

TBETA provides a simple graphical interface for building structures of two-terminal junctions of graphene nanoribbons (GNRs) at angles 60°, 120° and 180°. The electronic structure and transport properties of the constructed junctions are calculated using the nearest-neighbour tight-binding model in combination with the Landauer-Büttiker formalism and Green's function techniques.
