Strongly modulated conductivity in a perovskite ferroelectric field-effect transistor

Abstract
An all-perovskite field-effect transistor with a (Pb0.95La0.05)(Zr0.2Ti0.8)O3 gate insulator exhibits a strongly modulated room-temperature conductivity in a La1.94Sr0.06CuO4 channel. The channel conductivity is controlled by the hopping mechanism with variable jump length and determined by the Coulomb gap at the Fermi level.
