compute_linear_mass_density

sknano.core.structures.compute_linear_mass_density(*Ch, bond=None, element1=None, element2=None, **kwargs)

Compute nanotube linear mass density (mass per unit length) in grams/Å.

Parameters:

• *Ch –

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

• element2 (element1,) – Element symbol or atomic number of basis Atom 1 and 2
• bond (float, optional) – Distance between nearest neighbor atoms (i.e., bond length). Must be in units of Å. Default value is the carbon-carbon bond length in graphite, approximately \(\mathrm{a}_{\mathrm{CC}} = 1.42\) Å

Returns:

Linear mass density in units of g/Å.

Return type:

float
