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.

Parameters:

Parameters:	Ch : {`tuple` or `int`s} 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 Å. Default value is the carbon-carbon bond length in graphite, approximately $\mathrm{a}_{\mathrm{CC}} = 1.42$ Å
Returns:	float Linear mass density in units of g/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 Å. Default value is the carbon-carbon bond length in graphite, approximately $\mathrm{a}_{\mathrm{CC}} = 1.42$ Å

Returns:

float

Linear mass density in units of g/nm.
