Synthesis of Rh-carbon nanotube based heterostructures and their enhanced field emission characteristics.
Selective decoration of Rh nanospheres on acid functionalized carbon nanotubes has been demonstrated using Al as a sacrificial substrate. Remarkable field emission has been observed for this heterostructure as a high current density of 170 microA cm(-2) is generated at an ultra-low threshold of 300 V microm(-1), compared to much smaller values for Rh nanospheres and carbon nanotubes separately.
