Abstract

Temperature dependent thermoelectric power (TEP) and conductivity of the potassium doped bulk fullerene, K_xC₆₀, of different potassium doping concentrations are reported. The potassium contents are determined by chemical analyses. The resistivity drop at T=18K has been confirmed. Although, the room temperature resistivity values are more or less the same for various K_xC₆₀ samples (typically σ_RT = 10 S/cm), the TEP values are very much different. The sign of TEP is positive and its temperature dependence shows a big transition at around T = 150K. Interesting observation is that the TEP drops to zero at around 60K ∼ 80K for certain samples whose resistivity keep increasing at this temperature region.
