Non-degenerate Two Photon Absorption Spectra of Si Nanocrystallites
Toshiaki Iitaka, Toshikazu Ebisuzaki
Abstract
We propose an efficient linear-scaling time-dependent method for calculating nonlinear response function, and study the size effects in non-degenerate two photon absorption spectra of Si nanocrystallites by using semi-empirical pseudopotentials.
