Abstract :
The authors demonstrated decoration of Ru nanoparticles on the surface of double-walled CNTs (DWCNTs) using a chemical process and studied their field emission properties. Ru is more stable than the low work function alkali metals when exposed to oxygen. Moreover, the melting point of Ru is much higher than that of RuO2.
