Title: Optical spectra e-h interaction
Post by: ams_nanolab on July 10, 2015, 08:26

I understand from the manual that the Kubo-Greenwood formula is employed to calculate optical spectra in ATK. Is it a single particle K-G formula or it is also inclusive of e-h interactions in optical spectra ? Please reply early as I didn't get response for my earlier post.

It is the single particle states that are used for the optical spectrum, so it does not include exciton effects.
