Optical absorption in small BN and C nanotubes
L. Wirtz, V. Olevano, A. G. Marinopoulos +2
We present a theoretical study of the optical absorption spectrum of small boron-nitride and carbon nanotubes using time-dependent density-functional theory and the random phase ap…

Band structure of boron doped carbon nanotubes
Ludger Wirtz, Angel Rubio
We present {\it ab initio} and self-consistent tight-binding calculations on the band structure of single wall semiconducting carbon nanotubes with high degrees (up to 25 %) of bor…

Bound excitons in time-dependent density-functional-theory: optical and energy-loss spectra
A. Marini, R. Del Sole, A. Rubio
A robust and efficient frequency dependent and non-local exchange-correlation is derived by imposing time-dependent density-functional theory (TDDFT) to reproduce…
