Linear magnetoresistance in three-dimensional carbon nanostructure with periodic spherical voids
Abstract
We report electrical transport properties of carbon nanostructures with close-packed spherical voids. Under zero magnetic field, a non-metallic behavior is observed. With increasing magnetic field, magnetoresistance (MR) crosses over from quadratic to linear dependence. Longitudinal response, typically negligible in most materials, exhibits the same value and field-temperature dependence as transverse MR. At intermediate angles (0°–90°) MR is also found to be independent of the direction of magnetic field. It is reasoned that orientation-insensitive, linear MR is due to distorted current flow in the 3-dimensional porous structures of this system.
