Energy gap in superconducting fullerides: optical and tunneling studies
Daniel Koller, Michael C. Martin, Laszlo Mihaly +4
Tunneling and optical transmission studies have been performed on superconducting samples of Rb3C60. At temperatures much below the superconducting transition temperature Tc the en…
Polymeric alkali fullerides are stable in air
Daniel Koller, Michael C. Martin, Peter W. Stephens +5
Infrared transmission, electron spin resonance, and X-ray diffraction measurements show unambiguously that RbC and KC are stable in air, in contrast to RbC$_{60…
Infrared Spectroscopic Study of Phase Transisions in A1c60 Compounds (a=K,Rb,Cs)
Daniel Koller, Michael C. Martin, Laszlo Mihaly
Optical measurements on doped C films provide evidence for a transition from a high temperature conducting phase to a low temperature insulating phase in quenched RbC$_{…
Insulating and Conducting Phases of RbC60
Michael C. Martin, Daniel Koller, Xiaoqun Du +2
Optical measurements were performed on thin films of RbC, identified by X-ray diffraction as mostly material. The samples were subjected to various heat treatmen…
In-Situ Infrared Transmission Study of Rb- and K-Doped Fullerenes
Michael C. Martin, Daniel Koller, L. Mihaly
We have measured the four IR active molecular vibrations in as a function of doping . We observe discontinuous changes in the vibrational sp…
