Transport properties of the charge density wave quasi two-dimensional compounds (PO2)4(WO3)2m
Résumé
Single crystals of (PO2)4(WO3)2m have been studied for m values ranging from 4 to 12, by transport and x-ray diffraction measurements. Both the CDW temperatures and the room temperature resistivity are found to increase with m. This is discussed in relation with enhancements of the electronic low dimensional character and of the electron-electron interactions with m.
