compute_Natoms_per_tube

sknano.core.structures.compute_Natoms_per_tube(*Ch, nz=1)

Compute $N_{\mathrm{atoms/tube}}$

$$N_{\mathrm{atoms/tube}} = N_{\mathrm{atoms/cell}} \times n_{z-\mathrm{cells}}$$

Parameters:

• *Ch –

  Either a 2-tuple of ints or 2 integers giving the chiral indices of the nanotube chiral vector $\mathbf{C}_h = n\mathbf{a}_1 + m\mathbf{a}_2 = (n, m)$.

• nz ({int, float}) – Number of nanotube unit cells

Returns:

$N_{\mathrm{atoms/tube}}$

Return type:

int
