How to measure the Diameter of nanowire??
« on: October 7, 2016, 07:44 »
hello,
        how can we measure the Diameter of nanowire?? any litreture or idea, plz share..
        in case of carbon nanotube, the value of a=0.246 but i found c=4. something  for c. I want to measure Diameter of TiC nanotube and nanowire.
                       hope for reply, thanks

The diameter for non-circular objects is an ill-defined concept, so it depends a little bit on what you need it for? Do you just need to have a rough value or do you need a well-defined procedure to distinguish between nanowires which are superficially similar? In the first case, I would just do a manual measurement in the Viewer or Builder, but in the second case, you need an automated procedure. I know of an approach for nanoparticles, which can probably be adapted for nanowires. It is based on this paper: http://link.springer.com/article/10.1007%2FBF03024331

Thank u sir,
           i only want to include the rough value...
          so i will take average value from builder..
          thanks all of u experts...

See the book by Dresselhaus, Saito and Dresselhaus, Physical Properties of Carbon Nanotubes. It's THE text for nanotube physics.
