Abstract

Sizable single crystals of C₆₀ have been synthesized and doped with potassium. Above the superconducting transition temperature T_c, the electrical resistivity ρ(T) displays a classic metal-like temperature dependence. The transition to the superconducting state at T_c = 19.8 K is extremely sharp, with a transition width ΔT < 200 mK. In contrast to transport behavior of doped polycrystalline and granular thin films, no anomalous fluctuations are observed near T_c in single crystal specimens.
