Thin-film growth of the charge-density-wave oxide Rb0.30MoO3

We report on the thin-film fabrication of a charge-density wave (CDW) compound. Single-phase epitaxial films of the model CDW oxide Rb0.30MoO3 have been grown by pulsed-laser deposition. Detailed analyses show that the Rb0.30MoO3 films have mu m-size grains with the CDW chains oriented parallel to the substrate. On SrTiO3 (510), the CDW chains align into a single direction within the him plane, The electrical resistance of the films demonstrates a CDW state below about 182 K. Structures patterned in films will permit unprecedented studies of phase-coherent CDW transport, as well as the exploration of devices based on CDWs. (C) 1996 American Institute of Physics.
