Nonlocal Photorefractive Screening from Hot Electron Velocity Saturation in Semiconductors
... However, when ´"K# becomes a function of K and becomes complex, the dielectric function is nonlocal, causing a spatial shift between the intensity pattern and the resultant internal field. We show below that velocity saturation caused by intervalley scattering of photoinduced carriers is one such me ...
