Abstract

At room temperature a large magnetoresistance (MR) of up to 70% is observed in graphene. Both graphene size and surface functionality influence the MR behavior significantly. The conductivity increases linearly with increasing temperature and a unique negative permittivity over a wide frequency range from 103 to 106 Hz is observed at room temperature.
