Fabrication and electric-field-dependent transport measurements of mesoscopic graphite devices

Fabrication and electric-field-dependent transport measurements of mesoscopic graphite devices

We have developed a unique micromechanical method to extract extremely thin graphite samples. Graphite crystallites with thicknesses ranging from 10 - 100 nm and lateral size $\sim$ 2 $\mu$m are extracted from bulk. Mesoscopic graphite devices are fabricated from these samples for electric field dependent conductance measurements. Strong conductance modulation …
