Mesoscopic Free Path of Nonthermalized Photogenerated Carriers in a Ferroelectric Insulator

We show how finite-size scaling of a bulk photovoltaic effect-generated electric field in epitaxial ferroelectric insulating BaTiO_{3}(001) films and a photo-Hall response involving the bulk photovoltaic current reveal a large room-temperature mean free path of photogenerated nonthermalized electron...
