Chiral effects in normal and superconducting carbon nanotube-based nanostructures

چکیده
The novel phenomenon of chiral tunneling in metallic single-wall carbon nanotubes is considered. It is induced by the interplay of electrostatic and pseudomagnetic effects in electron scattering in chiral nanotubes and is characterized by an oscillatory dependence of the electron transmission probability on the nanotube chiral angle and the strength of the scattering potential. The appearance of a special Aharonov–Bohm-like phase in chiral tunneling affects various phasecoherent phenomena in nanostructures. We examine chiral effects in: i persistent currents in circular nanotubes, ii Josephson currents in nanotube-based SNS junctions, and iii resonant electron tunneling through chiral nanotube-based quantum dots. © 2010 American Institute of Physics. doi:10.1063/1.3518334

On the Mechanical Properties of Chiral Carbon Nanotubes
Carbon nanotubes (CNTs) are specific structures with valuable characteristics. In general, the structure of each nanotube is defined by a unique chiral vector. In this paper, different structures of short single-walled CNTs are simulated and their mechanical properties are determined using finite element method. For this aim, a simple algorithm is presented which is able to model the geometry o...

متن کاملImpurity Scattering in Carbon Nanotubes with Superconducting Pair Correlations
Effects of the superconducting pair potential on the impurity scattering processes in metallic carbon nanotubes are studied theoretically. The backward scattering of electrons vanishes in the normal state. In the presence of the superconducting pair correlations, the backward scatterings of electronand hole-like quasiparticles vanish, too. The impurity gives rise to backward scatterings of hole...

Due to emergence of serious obstacles by scaling of the transistors dimensions, it has been obviously proved that silicon technology should be replaced by a new one having a high ability to overcome the barriers of scaling to nanometer regime. Among various candidates, carbon nanotube (CNT) field effect transistors are introduced as the most promising devices for substituting the silicon-based ...
