Due to imminent applications in nanoelectronics it is of high interest to understand the precise conductance properties of bent or deformed carbon nanotubes. Since low-energy electronic excitations in graphene behave like massless Dirac fermions the current flow can be approximated semiclassically and used as a guide in the design of conducting nanotube-elements. Taking into account the curvature effects as well as an emerging inhomogeneous pseudo-magnetic field we calculate the current flow paths theoretically and compare them with numerical simulations of the full electronic transport.
