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…
Observation and Assignment of Silent and Higher Order Vibrations in the Infrared Transmission of C60 Crystals
Michael C. Martin, Xiaoqun Du, John Kwon +1
We report the measurement of infrared transmission of large C60 single crystals. The spectra exhibit a very rich structure with over 180 vibrational absorptions visible in the 100…
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…
