文摘
Thin films of the molecular conductor TTF–TCNQ are grown using chemical vapour deposition (CVD) on stainless steel conversion coating (SSCC) substrates. The fractal-like morphology and high adsorption properties of SSCC improve the surface coverage in CVD-grown thin films. 1 μm thick, oriented, conductive deposits are obtained and studied by SEM, IR, XRD and conductivity measurements. Additionally, an unexpected ability of SSCC to induce nanowire formation is shown. By successively dipping SSCC in TTF and TCNQ solutions, typically 20nm×20μm conducting wires and ribbons, and occasionally loops, form on the substrates. They could be separated from the surface and were studied by TEM, AFM and current–voltage measurements.
