Chart above: The assignment chart for single-walled carbon nanotubes based on their (n,m) index. At the left hand side of the chart is the index “n” and at the bottom of the chart is the index “m”. The achiral zig-zag tubes with an index (n, 0) fall in the first column of the table. The diagonal row at the extreme right, colored in blue is the family of armchair tubes with a chiral angle of 30o . Semimetals (see text for definition) marked in green fall in diagonal fashion as well. The rest of the cells in yellow represent semiconducting tubes. The blue and red dotted lines that run across the table divide the table into bins where SWNT of approximately same diameter and chiral angle ranges respectively could be located. For the low diameter tubes marked with an asterisk, the predicted values do not match closely.
