Abstract
Langmuir-Blodgett films of C-60 were doped with potassium, and the dop ing was followed insitu by both microwave low-field signal(LFS) and el ectron spin resonance. The superconducting critical temperature was T- c (onset) = 12.9 = K for a nominal 14-layer film at optimum doping. Th e four-probe conductivity of an underdoped film as a function of tempe rature showed semiconducting behavior.
