Pressure- and orientation-dependent linear optical absorption spectra of radially deformed single-walled carbon nanotubes

Based upon the Slater–Koster tight‐binding model and the gradient approximation, we investigate the linear optical properties of radially deformed single‐walled carbon nanotubes (SWNTs). It is found that, for the armchair tubes, the radial pressure may make the absorption peaks exhibited in the perf...
