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
