For the following chiral index (n, m) SWCNTs compute the diameter, electronic structure, and density of an individual nanotube 500 nm in length (no end caps). Show your work. Note the math involved is only geometry (vectors) and algebra. HINTS: You may want to define a translational vector normal to the chiral vector. You need to consider something called the van der Waals radius in the density calculations. d. (9,0)
