sknano.structures.compute_linear_mass_density(*Ch, *, bond=None, element1=None, element2=None, **kwargs)[source][source]

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


*Ch : {tuple or ints}

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

element1, element2 : {str, int}, optional

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 . Default value is the carbon-carbon bond length in graphite, approximately \(\mathrm{a}_{\mathrm{CC}} = 1.42\)



Linear mass density in units of g/nm.
