Time-resolved observation of band-gap shrinking and electron-lattice thermalization within X-ray excited gallium arsenide
Femtosecond X-ray irradiation of solids excites energetic photoelectrons that thermalize on a timescale of a few hundred femtoseconds. The thermalized electrons exchange energy with the lattice and heat it up. Experiments with X-ray free-electron lasers have unveiled so far the details of the electr...
