Abstract:
Experimentally is confirmed that helically coiled carbon nanotube (HCCNT) could be used as a small solenoid for generating spatially localized magnetic field. Current distribution during diffusive electron transport followed by electron-phonon scattering likewise inductivity of this quantum conductor depends on electric field. Despite slightly lower electron mobility in HCCNTs compared to straight single wall carbon nanotubes, coiled nanotubes are attractive for application as nonlinear nano-solenoids. Non-equilibrium electron distribution functions derived as solutions of Boltzmann transport equation are used to predict average helical radius of current flow as a function of electric field intensity. Qualitative prediction of nonlinear inductivity of HCCNT is given.
