Abstract
In this paper, we have investigated the transport properties of the Dirac fermions on a topological insulator surface in the presence of external electric and magnetic fields. For this reason, firstly we obtain the eigen energies (or eigenvalues) by using the Dirac Hamiltonian of the system for transmitted electrons via the surface and the Lorentz transformations. The conductance of the system is calculated by Landauer equation. Also, the effects of electric and magnetic fields are investigated on the conductance and Fano factor effect. The application of the present results may be useful in designing devices based on molecular electronics in nanoscale.
