Ultrafast charge relocation in an ionic crystal probed by femtosecond x-ray powder diffraction
Transient electron density maps of potassium dihydrogen phosphate(KH2PO4, KDP) are derived from femtosecond x-ray powder diffraction patterns. Upon photoexcitation, the low-frequency TO soft mode is elongated impulsively and modulates the electronic charge distribution on the length scale of interat...
