Ultrafast Photovoltaic Response in Ferroelectric Nanolayers
We show that light drives large-amplitude structural changes in thin films of the prototypical ferroelectric PbTiO[subscript 3] via direct coupling to its intrinsic photovoltaic response. Using time-resolved x-ray scattering to visualize atomic displacements on femtosecond time scales, photoinduced...
