Abstract
An analytic approach is developed in the nearest neighbor approximation for describing electron transport through axially symmetric junctions of zigzag and armchair nanotubes. This method yields an analytic expression for the electron transmission probability and can be used to establish selection rules for electron scattering. Oscillations in the gap width in the electron transmission spectrum are predicted as a function of the nanotube diameter and the minimum gap size is determined. The thresholds for the appearance of steps in the electron transmission coefficient are also found and it is shown that, except in its initial section, the origin of the steps is associated with the electronic characteristics of armchair nanotubes, alone.
