Construction of Carbon Nanotubes with Different Parameters TsaiChung-Jung ZhengJie NussinovRuth 2013 <p>Four carbon nanotubes with different wrapping constants <i>(n<sub>1</sub>, n<sub>2</sub>)</i> are constructed with the 2-D lattice (<i>a</i> = 2.459512, <i>b</i> = 2.459512, <i>γ</i> = 120), P6 lattice symmetry, and one-carbon fractional coordinates (1/3, 2/3, 0). In each nanotube, there are <i>n</i><sub>1</sub>*7 cells shown in cyan with the origin of the lattice highlighted in red and one complete wrapping round in magenta.</p>
