Raman Scattering From the Superconductor Niobium-Diselenide
… 33 K 2H-NbSe(,2) distorts into an incommensurate charge density wave (CDW) state. The Raman spectrum shows amplitude modes of A and E symmetry near 40 cm('-1) induced by the CDW. At 7 K this material becomes superconducting, and at 2 K we observe additional Raman peaks near 20 cm('-1), one each of …

An X-ray study of charge-density-wave pinning and a measurement of the thermal conductivity in blue bronze
Two different aspects of the charge-density-wave (CDW) state were studied in the quasi-onedimensional metal blue bronze (Ko.3oMo03). In the primary experiment reported in this thesis, pinning of the CDW phase by lattice imperfections was examined. Pinning determines most of the dynamics of CDW …

Coupled one dimensional electron systems and stripe phases of high temperature superconductors
… chapter one, I consider the problem of the Local Density of States for spin-gapped one-dimensional charge density wave (CDW) states and Mott insulators in the presence of a hard-wall boundary. I calculate the boundary contribution to the single-particle Green function in the low-energy limit using …
