Nanopore and tunneling resonance in an open kink in carbon nanotubes
Alex Kleiner
In weakly buckled carbon nanotubes, the kink is an open, ovalized constriction where molecular-sized analytes and ions can pass. Moreover, in semiconducting tubes, the kink has an…
Bandgaps of bent and buckled carbon nanotubes
Alex Kleiner
Carbon nanotube's large electro-mechanical coupling and robustness makes them attractive for applications where bending and buckling is present. But the nature of this coupling is…
Spin stripes in nanotubes
Alex Kleiner
It is shown here that electrons on the surface of a nanotube in a perpendicular magnetic field undergo spin-chirality separation along the circumference. Stripes of spin-polarizati…
Curvature, hybridization, and STM images of carbon nanotubes
Alex Kleiner, Sebastian Eggert
The curvature effects in carbon nanotubes are studied analytically as a function of chirality. The pi-orbitals are found to be significantly rehybridized in all tubes, so that they…
Band gaps of primary metallic carbon nanotubes
Alex Kleiner, Sebastian Eggert
Primary metallic, or small gap semiconducting nanotubes, are tubes with band gaps that arise solely from breaking the bond symmetry due to the curvature. We derive an analytic expr…
