Looking at [1], the price of low-volume of single gram of high quality carbon nanotubes is $250. Volume prices go further down. According to [2] carbon nanotube layer could weight 0.1 gram/square-meter. So basically we'll spend $25 for a square meter of chips(more precisely dies) - that's fractions of a cent per gbyte.Pretty insignificant.
