Abstract

The calculations of the optical absorption spectrum of Si with the novel time-dependent exact-exchange (TDEXX) method was reported. The nature of the dynamic and nonlocal orbital based EXX kernel was studied exhibiting the q→0 behavior of the exact F and generating excitonic features in the spectrum. It was shown that the Coulomb coupling of electron-hole pairs and the correct long-wavelength behavior in the kernel is crucial for the proper description of excitonic effects in semiconductors.
