First-Principles Modeling of Pt/LaAlO3/SrTiO3 Capacitors Under an External Bias Potential
Claudio Cazorla, Massimiliano Stengel
We study the electrical properties of Pt/LaAlO3/SrTiO3 capacitors under the action of an external bias potential, using first-principles simulations performed at constrained electr…
Electrostatic stability of insulating surfaces: Theory and applications
Massimiliano Stengel
We analyze the electrostatic stability of insulating surfaces in the framework of the bulk modern theory of polarization. We show that heuristic arguments based on a fully ionic li…
Electrochemical ferroelectric switching: The origin of polarization reversal in ultrathin films
N. C. Bristowe, Massimiliano Stengel, P. B. Littlewood +2
Against expectations, robust switchable ferroelectricity has been recently observed in ultrathin (1 nm) ferroelectric films exposed to air [V. Garcia , Nature {\bf 460},…
Band alignment at metal/ferroelectric interfaces: insights and artifacts from first principles
Massimiliano Stengel, Pablo Aguado-Puente, Nicola A. Spaldin +1
Based on recent advances in first-principles theory, we develop a general model of the band offset at metal/ferroelectric interfaces. We show that, depending on the polarization of…
