Flexible thin film transistors (TFT) were fabricated with randomly oriented single-walled carbon nanotubes (SWNTs) synthesized selectively on a designed array of catalyst photoresists using the plasma-enhanced chemical vapor deposition (PECVD) method. The process involves SWNTs growth on SiO2/Si substrates, followed by transfer-printing of tubes onto thin, flexible sheets of plastic. Electrical measurements...
Microwave plasma enhanced chemical vapor deposition (MPECVD) was applied in growing carbon nano tubes (CNTs) on sodium free glass with different interface layer materials. Surface morphology and field emission characteristics of as grown CNTs were measured. Three different materials: titanium(Ti), gold(Au) and indium tin oxide (ITO) thin films were prepared on glass first as the interface role between...
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...
The composite structure of silicon tips and vertical aligned carbon nanotubes (CNTs) was prepared using plasma enhanced hot filament chemical vapor deposition (PE-HFCVD) method on the silicon wafer, and Au/Ni film coated on the substrate was considered as a catalyst. High proportion hydrogen of 96% volume percentage and high total pressure are used during preparing process, and the pure CNTs, pure...
Carbon nanotubes (CNTs) were synthesized in atmospheric pressure microwave plasma torch in the mixture of argon, methane and hydrogen on the silicon substrate with SiO2 overlayer and a thin top iron film serving as a catalyst. This deposition technique is unique because of its simplicity and high CNT growth rate but it is still under investigation as concerns exits around its reproducibility. CNTs...
