Electronic screening as a design lever in La-doped BaTiO3: coupling between polarization, dielectric response, and optical anisotropy

Donor substitution is an effective strategy for modifying the coupled ferroelectric, dielectric, electronic, and optical properties of perovskite oxides by altering lattice distortion and electronic screening. In this work, first-principles calculations were performed to examine the microscopic effect of La donor subst...
