文摘
- •
Electronic properties of carbon nanotube homo-junctions have been studied.
- •
An Extended Hückel theory/Non Equilibrium Green’s Function based model was applied.
- •
Conductance oscillations for changes in alignment between the tubes were found.
- •
Oscillations are ascribed to coupling, carrier scattering and quantum interference.
