Characterization of epitaxially grown films of (TTF) (TCNQ)

Epitaxial films of the highly conducting organic charge-transfer salt tetrathiafulvalinium tetracyanoquinodimethanide, (TTF) (TCNQ), grown on NaCl substrates were analyzed using electron diffraction and electron and polarized optical microscopy techniques. The films were found to orient with the high-conductivity (TTF) (TCNQ) b axis along [110] directions of the NaCl. Preliminary optical, infrared, and electrical data obtained on these films are also presented. © 1974 American Institute of Physics.
