Abstract

Scanning tunneling microscopy (STM) studies of a series of single crystals of organic conductors revea; topographical and electronic structure of specific crystal planes, these planes exhibiting molecularly flat large areas. For example, scanning tunneling microscopy (STM) images of the (001) face of the organic conductors (TMTSF)₂X (TMTSF = tetramethyltetraselenafulvalene; X = ClO₄-, ReO₄-) reveal significant differences in the local density of states associated with the transverse band structure in these two compounds. STM studies of the (001) and (010) faces of [(η-C₅Me₅)₂Ru(η⁶,η⁶-[2₂](1,4)cyclophane)]²+[TCNQ]₄^2- reveal tunneling current corrugation attributed to tunneling into the conduction band of a antiferromagnetic 2k_F charge density wave (CDW) structure. The CDWs also exhibit antiphase modulation at a/2 with respect to adjacent stacks, consistent with appreciable interstack Coulomb interactions and contributions from the magnetic 4k_F structure.
