- Layer-by-layer assembly;
Metal nanowires coated with multilayer films of (TiO2/W12O41)3(PAN/SWNT)3PAN (12 nm thick; PAN: Polyaniline; SWNT: single-walled carbon nanotube) are synthesized using different, templated, layer-by-layer assembly techniques. Their I–V characteristics indicate a built-in p–n junction at the TiO2/PAN interface (rectification ratio >120 at 3 V). Films grown on planar substrates have similar thickness, morphology, and electrical properties.
