متن کاملStrain-Engineered Oxygen Vacancies in CaMnO3 Thin Films.
We demonstrate a novel pathway to control and stabilize oxygen vacancies in complex transition-metal oxide thin films. Using atomic layer-by-layer pulsed laser deposition (PLD) from two separate targets, we synthesize high-quality single-crystalline CaMnO3 films with systematically varying oxygen vacancy defect formation energies as controlled by coherent tensile strain. The systematic increase...

متن کاملVacancies Job in Oxide Perovskite Thin Films
Point defects can affect considerably the structural, magnetic, and transport properties of perovskite-structure materials with chemical formula ABO3. Oxygen vacancies (VO), for example, enable ionic conductivity in perovskite-based solid solutions to be used for electrochemical applications such as solid oxide fuel and electrolysis cells [1]. Likewise, VO can distort significantly the equilibr...
متن کاملFerroelectricity in strain-free SrTiO3 thin films.
Biaxial strain is known to induce ferroelectricity in thin films of nominally nonferroelectric materials such as SrTiO3. By a direct comparison of the strained and strain-free SrTiO3 films using dielectric, ferroelectric, Raman, nonlinear optical and nanoscale piezoelectric property measurements, we conclude that all SrTiO3 films and bulk crystals are relaxor ferroelectrics, and the role of str...
