Ferroics: Magnetic-Compass Lattice and Optical Phonon Dispersions of Dipolar Crystals

October 12, 2021
Author(s)
Takeshi Nishimatsu, U Waghmare, Yoshiyuki Kawazoe, Benjamin P. Burton, Kazutaka Nagao, N. Saito
We report a simple safe and attractive pedagogic demonstration with magnetic compasses that facilitates an intuitive understanding of the concept that ferromagnetism and ferroelectricity do not result from dipole-dipole interactions alone. Phonon

Electric field induced phase transition in vertical MoTe2 and Mo1-xWxTe2 based RRAM devices

December 10, 2018

Feng Zhang, Sergiy Krylyuk, Huairuo Zhang, Cory A. Milligan, Dmitry Y. Zemlyanov, Leonid A. Bendersky, Albert Davydov, Joerg Appenzeller, Benjamin P. Burton, Yugi Zhu
Transition metal dichalcogenides have attracted attention as potential building blocks for various electronic applications due to their atomically thin nature and polymorphism. Here, we report an electric-field-induced structural transition from a 2H

First-principles phase diagram calculations for the carbonate quasibinary systems CaCO(sub3)-ZnCO(sub3), CdCO(sub3)-ZnCO(Sub3), CaCO(sub3)-CdCO(sub3) and MgCO(Sub3)-ZnCO(sub3)

Z.T.Y. Liu, Benjamin P. Burton, S. V. Khare, P. Sarin
Quasibinary solid solutions of calcite-structure carbonate minerals play an important role in rock formation. We have investigated solid solutions with cations such as Ca, Cd, Mg and Zn by performing first-principles phase diagram calculations for Ca1

Order-Disorder and Phase Separation

October 28, 2015
Author(s)
Benjamin P. Burton
Order-disorder and phase separation in condensed solutions of two or more components are similar processes that are typically driven by energetics of opposite sign. The components may be: different atomic species in alloys or solid solutions; atoms and

Effects of Vacancies on Properties of Relaxor Ferroelectrics: A First-Principles Study

February 13, 2007
Author(s)
L Bellaiche, Jorge Iniguez, Eric J. Cockayne, Benjamin P. Burton
A first-principles-based model is developed to investigate the influence of lead vacancies on the properties of relaxor ferroelectric Pb(Sc1/2Nb1/2)O3 (PSN). Lead vacancies generate large, inhomogeneous, electric fields that reduce barriers between energy
