  • Abstract
    The room-temperature THz spectrum of graphite nanoplatelets shows a free carrier absorption at zero frequency with an electronic scattering rate of 175 cm-1 (3.3 times 1013 rad/s) and plasma frequency of 1675 cm-1. The lack of a major change in Drude plasma frequency down to 4.2 K implies any band gaps in graphite nanoplatelets are less than 1 meV.
