Ferroelectricity in strained Ca0.5Sr0.5TiO3 from first principles

We present a density-functional theory investigation of strained Ca[subscript 0.5]Sr[subscript 0.5]TiO[subscript 3] (CSTO). We have determined the structure and polarization for a number of arrangements of Ca and Sr in a 2×2×2 supercell. The a and b lattice vectors are strained to match the lattice...
