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…
Vibrational Study of 13C-enriched C60 Crystals
Michael C. Martin, J. Fabian, J. Godard +3
The infrared (IR) spectrum of solid C60 exhibits many weak vibrational modes. Symmetry breaking due to 13C isotopes provides a possible route for optically activating IR-silent vib…
Infrared and Raman Evidence for Dimers and Polymers in Rb1C60
Michael C. Martin, Daniel Koller, A. Rosenberg +2
The infrared- and Raman-active vibrational modes of C60 were measured in the various structural states of Rb1C60. According to earlier studies, Rb1C60 has an structure at tem…
No Far-Infrared-Spectroscopic Gap in Clean and Dirty High-T Superconductors
D. Mandrus, Michael C. Martin, C. Kendziora +3
We report far infrared transmission measurements on single crystal samples derived from BiSrCaCuO. The impurity scattering rate of the samples was varied by…
