Fig. 3: XTA spectra dominated by the effect of core-exciton Coulomb screening of photoexcited carriers.
From: Dynamic control of X-ray core-exciton resonances by Coulomb screening in photoexcited semiconductors

Calculated contributions of the Coulomb screening (shaded blue areas) and Pauli blocking (shaded red areas) by photoexcited carriers to the XTA spectra (black curves) at the a Zn K-edge and b Zn L3-edge at a time delay of 100 ps. Inset: Pauli blocking contribution at the Zn K-edge.
