binding energy of hexagonal nanowire

[Sumit2506]

If we are going to analyse bulk structure of InAs it contains only two atoms however if we make the hexagonal nanowire by this of 5A diameter it contains more then 30 atoms, so how we can find out the binding energies for hexagonal nanowire please help me out........



Thanks with Regards

You rescale the energy of the bulk system to have similar number of atoms as the nanowire, i.e. 30/2=15
