A new plasma source is developed by introducing 'Buckminsterfullerene', C60, particles into a low-temperature (about 0.2 eV) potassium plasma column confined by a strong axial magnetic field, which consists of electrons, positive K+ ions and large negative C60- ions. Drastic changes in characteristics of thin films formed by using the plasma are observed in accordance with bias control of fluxes and energies of K+ and C60- ions coming into contact with substrates. It is hoped that this ultra-fine-particle plasma will be useful for producing C60-based materials with unique functions such as alkali fullerides, endohedral metallofullerenes and polymers.
