Journal ArticleDOI
Room-temperature ferroelectricity in strained SrTiO3.
J. H. Haeni,Patrick Irvin,Wontae Chang,Reinhard Uecker,P. Reiche,Y. L. Li,Somnath Choudhury,Wei Tian,Marilyn E. Hawley,B. Craigo,Alexander K. Tagantsev,Xiaoqing Pan,Stephen K. Streiffer,Long Qing Chen,Steven W. Kirchoefer,Jeremy Levy,Darrell G. Schlom +16 more
TL;DR: It is shown that epitaxial strain from a newly developed substrate can be harnessed to increase Tc by hundreds of degrees and produce room-temperature ferro electricity in strontium titanate, a material that is not normally ferroelectric at any temperature.
Journal ArticleDOI
A Phenomenological Thermodynamic Potential for BaTiO3 Single Crystals
TL;DR: In this paper, a phenomenological thermodynamic potential was constructed based on the properties of bulk BaTiO3 single crystals using an eighth-order polynomial of Landau-Devonshire expansion.
Journal ArticleDOI
Temperature-strain phase diagram for BaTiO3 thin films
Y. L. Li,Y. L. Li,Long Qing Chen +2 more
TL;DR: In this paper, the shifts of ferroelectric phase transition temperatures and domain stabilities of BaTiO3 thin films as a function of strain and temperature were studied using phase-field simulations.
Journal ArticleDOI
c-axis oriented epitaxial BaTiO3 films on (001) Si
V. Vaithyanathan,V. Vaithyanathan,V. Vaithyanathan,J. Lettieri,J. Lettieri,Wei Tian,Wei Tian,Alok Sharan,A. Vasudevarao,Y. L. Li,Y. L. Li,A. Kochhar,Hongzhou Ma,Jeremy Levy,Paul Zschack,Joseph C. Woicik,Long Qing Chen,Venkatraman Gopalan,Darrell G. Schlom,Darrell G. Schlom +19 more
TL;DR: In this paper, a c-axis oriented epitaxial BaTiO3 film was grown on (001) Si by reactive molecular-beam epitaxy and the orientation relationship between the film and substrate was investigated.
Journal ArticleDOI
Effect of substrate-induced strains on the spontaneous polarization of epitaxial BiFeO3 thin films
J. X. Zhang,Y. L. Li,Yi Wang,Zi Kui Liu,Long Qing Chen,Ying-Hao Chu,F. Zavaliche,Ramamoorthy Ramesh +7 more
TL;DR: In this article, a single-domain thermodynamic theory is employed to predict the spontaneous polarizations of (001)c, (101)c and (111)c oriented epitaxial BiFeO3 thin films grown on dissimilar substrates.
