The charge density wave instability in the quasi-two-dimensional conductor thallium purple molybdenum bronze TlMo 6 O 17 was carefully examined by studying the temperature dependence of resistivity, thermoelectric power (TEP) behavior and magnetic susceptibility. A metal-to-metal transition was confirmed near 110 K in TlMo 6 O 17 due to the partial opening of a gap at the Fermi surface and the driving of charge density wave.

Recent experiments seem to indicate that the superconductivity in Ba 1−x K x BiO 3 type compound occurs in the metallic state before its transformation to the charge density wave (CDW) state as the doping parameter x is reduced. Assuming the local breathing modes around Bi-atoms are responsible for both the CDW and superconducting states. We show that the superconducting transition temperature T c can be substantially enhanced as x approaches the CDW instability from the metallic side. Similar calculation has been carried out for a two-dimensional system and the results are in qualitative agreement with a recent Monte Carlo simulation.
