We have developed a unique micromechanical method to extract extremely thin graphite samples. Graphite crystallites with thicknesses ranging from 10 to 100 nm and lateral size similar to2 mum are extracted from bulk. Mesoscopic graphite devices are fabricated from these samples for electric field-dependent conductance measurements. Strong conductance modulation as a function of gate voltage is observed in the thinner crystallite devices. The temperature-dependent resistivity measurements show more boundary scattering contribution in the thinner graphite samples. (C) 2005 American Institute of Physics.
