Abstract: The absence of backscattering in metallic nanotubes as well as perfect Kleintunneling in potential barriers in graphene are the prominent electroniccharacteristics of carbon nanostructures. We show that the phenomena can beexplained by a peculiar supersymmetry generated by a first order Hamiltonianand zero order supercharge operators. Like the supersymmetry associated withsecond order reflectionless finite-gap systems, it relates here the low-energybehavior of the charge carriers with the free particle dynamics.
