title = "Electro-optic Raman observation of low temperature phase transitions in ZnO-BaTiO 3-ZnO heterostructures",
abstract = "Temperature-dependent electro-optic Raman measurements performed on ZnO-BaTiO 3-ZnO heterostructures grown by pulsed laser deposition on (0001) sapphire reveal a high temperature phase transition point of BaTiO 3 resulting from the leakage current within the sample, a persisting ferroelectric phase as well as a voltage driven progressive structural change in the BaTiO 3 layer. Dielectric measurements confirm the cubic - tetragonal (384 K), tetragonal-orthorhombic (245 K), and orthorhombic- rhombohedral (131 K) phase transition points.",
