Abstract

The thermoelectric power (TEP) and resistivity of graphitic nanotubules were measured under high pressure up to ∼ 10 GPa using a laser-heated diamond anvil cell technique. The electrical resistivity decreased rapidly with increasing pressure up to ∼ 2 GPa and thereafter it decreased monotonically with pressure. When pressure is applied along the tube axis TEP exhibits weak pressure dependence. Whereas for pressure applied perpendicular to the tubules TEP increases up to ∼ 2 GPa followed by a gradual decrease. The changes observed in both TEP and resistivity are reversible.
