The electrical conductance of a mesoscopic normal metal/charge density wave/normal metal (N/C/N) heterostructure is calculated. Geometrical resonances due to quantum interference are predicted in the quasi-particle transmission probability. At low temperatures the collective CDW motion is dissipative only in the vicinity of the contacts. The mechanism of current conversion can be understood in analogy...
The quasi-particle transport of normal metal/insulator/charge density wave (N/I/C) junctions with density modulation normal to the interface is investigated theoretically. In contrast to superconductors or ferromagnets, the tunnel current depends strongly on the macroscopic phase of the charge density wave condensate and does not approach the bulk density of states for strong barrier potentials. Characteristic...
