Microscopic piezoelectric behavior of clamped and membrane (001) PMN-30PT thin films
A. Brewer, S. Lindemann, B. Wang +13
Bulk single-crystal relaxor-ferroelectrics, like Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT), are widely known for their large piezoelectricity. This is attributed to polarization rotation wh…
Nature of the Structural Symmetries Associated with Hybrid Improper Ferroelectricity in Ca3X2O7
S. Liu, H. Zhang, S. Ghose +8
In hybrid improper ferroelectric systems, polarization arises from the onset of successive nonpolar lattice modes. In this work, measurements and modeling were performed to determi…
Possibility of Realizing Quantum Spin Hall Effect at Room Temperature in Stanene/Al2O3(0001)
Hui Wang, S. T. Pi, J. Kim +3
Two-dimensional quantum spin Hall (QSH) insulators with reasonably wide band gaps are imperative for the development of various innovative technologies. Through systematic density…
Searching for Large-gap Quantum Spin Hall Insulators: Boron-Nitride/(Pb, Sn)/α-Al2O3 Sandwich Structures
Hui Wang, D. Lu, J. Kim +3
Topological insulators hold great potential for efficient information processing and storage. Using density functional theory calculations, we predict that a honeycomb lead monolay…
Modulation of the Curie Temperature in Ferromagnetic/Ferroelectric Hybrid Double Quantum Wells
N. Kim, H. Kim, J. W. Kim +2
We propose a ferromagnetic/ferroelectric hybrid double quantum well structure, and present an investigation of the Curie temperature (Tc) modulation in this quantum structure. The…
