Probing Quantum Confinement and Electronic Structure at Polar Oxide Interfaces
Danfeng Li, Sébastien Lemal, Stefano Gariglio +5
Polar discontinuities occurring at interfaces between two different materials constitute both a challenge and an opportunity in the study and application of a variety of devices. I…
Atomic Scale Measurement of Polar Entropy
Debangshu Mukherjee, Sergei Prokhorenko, Leixin Miao +4
Entropy is a fundamental thermodynamic quantity that is a measure of the accessible microstates available to a system, with the stability of a system determined by the magnitude of…
Vibrational and dielectric properties of the bulk transition metal dichalcogenides
Nicholas A. Pike, Antoine Dewandre, Benoit Van Troeye +2
Interest in the bulk transition metal dichalcogenides for their electronic, photovoltaic, and optical properties has grown and led to their use in many technological applications.…
Direct magnetization-polarization coupling in BaCuF fluoride
A. C. Garcia-Castro, W. Ibarra-Hernandez, Eric Bousquet +1
Despite oxides and some fluorides perovskites have emerged as prototypes of multiferroic and magnetoelectric materials, they have not impacted real devices. Unfortunately, their wo…
Giant photoinduced lattice distortion in oxygen-vacancy ordered SrCoO2.5 thin films
Bingbing Zhang, Xu He, Jiali Zhao +8
Despite of the tremendous efforts spent on the oxygen vacancy migration in determining the property optimization of oxygen-vacancy enrichment transition metal oxides, few has focus…
Giant electrocaloric response in the prototypical Pb(Mg,Nb)O relaxor ferroelectric from atomistic simulations
Zhijun Jiang, Y. Nahas, S. Prokhorenko +4
An atomistic effective Hamiltonian is used to investigate electrocaloric (EC) effects of Pb(MgNb)O (PMN) relaxor ferroelectrics in its ergodic regime, and sub…
