Abstract
The high dielectric constant of doped ferroelectric KTa 1-xNbxO3 is shown to increase dielectric screening of electron scatterers, and thus to enhance the electronic mobility, overcoming one of the key limitations in the application of functional oxides. These observations are based on transport and optical measurements as well as band structure calculations.
