No small measure: Origins of nanorod diameter discovered
Date:3/19/2009

the fundamental diameter of nanorods, Huang shows in the new study. The rate at which atoms are being deposited onto the surface, as well as the temperature of the surface, also factor into the equation.

"Surface steps are effective in slowing down the mass transport of surface atoms, and aggregated surface steps are even more effective," Huang said. "This extra effectiveness makes the diameter of nanorods around 100 nanometers; without it the diameter would go up to 10 microns."

Beyond advancing scientific theory, Huang said the discovery could have implications for developing photonic materials and fuel cell catalysts.
