Dear CCL mates

Can some one let me know how can i generate the coordinates of different na= notubes and nano wires of different materials

eg. different types of Si nanotubes/nano wires.

thanks in advance

Hi

what essentially is the difference between nanotube and a nano wire ..?

Is it that nanotube is hollow with a particular dia
and wire has atoms in the core also ...?

thanks in advance

I would be happy to welcome the one or other of you at our symposium. (Not all of you ;-) , since we have only about 20 seats left.)
