摘要：

The conductance of a junction connecting two carbon nanotubes of differing diameter is calculated in magnetic fields perpendicular to the tube axis. The relative importance of mixing between different valleys exhibits a characteristic change depending on the effective strength of the magnetic field in the two tubes. The conductance depends only on the component of the magnetic field in the direction of the pentagonal and heptagonal rings.
