Negative temperature coefficient of single-walled carbon nanotube-gold nanoparticle hybrid structures
Single-walled carbon nanotubes (SWNTs) were grown on gold nanoparticle (GNP) coated quartz substrates by alcohol catalytic chemical vapor deposition. The GNP coated substrates were coated with Co catalyst by a dip-coat method. The growth was then carried out at 800°C under a pressure of 10 Torr in a...
