Electric and magnetic response of multi-wall carbon nanotubes

Abstract

The distribution of induced electric field around a carbon nanotube is calculated in an external field applied perpendicular to the axis. In multi-wall nanotubes, the field is screened out almost completely by a few outer walls. The field distribution is calculated also for a magnetic field, showing that NMR line is broadened roughly in proportion to the wall number in multi-wall nanotubes. ©2008 The Physical Society of Japan.
