The electrical transport behavior of carbon nanotube field-effect transistors (CNT-FETs) decorated with gold nanoparticles (NPs) has been investigated. After decoration with Au NPs, the Ion/Ioff ratios of nanotube FETs decrease and some of the p-type devices even change into metallic ones. The Au NPs decrease the contact resistances between the CNTs and metal electrodes, and accordingly increase the...
Patterned carbon nanotube arrays (PCNTAs) with reduced density and length were developed with polystyrene sphere masked catalyst dots followed by the plasma enhanced chemical vapour deposition method. The nanotubes were then uniformly coated with electropolymerised polypyrrole (PPy). The coating thickness was conformally adjustable. Gold nanoparticles (AuNP) together with glucose oxidase (Gox) were...
Highly-fluorescent, water-soluble and ambient-stable nanohybrids based on multi-walled carbon nanotubes and gold nanoparticles (Au@MWNTs) with high-density and well-distributed Au nanoparticles were obtained assisted by organic optoelectronic active molecules as an interlinker and stabilizer via a facile in-situ fabrication method in aqueous solution, and were confirmed by TEM, SEM, EDX, UV-Vis measurements...
We have developed a simple and practical method to enhance the electrical conductivity of single-walled carbon nanotube (SWNT) films without loss of their transparency. In order to achieve an enhanced conductivity of transparent SWNT films, we carried out the formation of gold nanoparticles through the reduction of gold ions (Au3+) onto the SWNT films which manufactured by the vacuum filtration method...
