Domain-Wall Mediated Polarization Switching in Ferroelectric AlScN: Strain Relief and Field-Dependent Dynamics
Xiangyu Zheng, Charles Paillard, Dawei Wang +4
While scandium-doped aluminum nitride (AlScN) exhibits robust ferroelectricity and excellent thermal stability, its utility is limited by an exceptionally high coercive field ($E_c…
Microscopic Origin of the Electric Dzyaloshinskii-Moriya Interaction
Peng Chen, Hong Jian Zhao, Sergey Prosandeev +2
The microscopic origin of the electric Dzyaloshinskii-Moriya interaction (eDMI) is unveiled and discussed by analytical analysis and first-principles based calculations. As similar…
A rhombohedral ferroelectric phase in epitaxially-strained Hf0.5Zr0.5O2 thin films
Yingfen Wei, Pavan Nukala, Mart Salverda +10
After decades of searching for robust nanoscale ferroelectricity that could enable integration into the next generation memory and logic devices, hafnia-based thin films have appea…
Raman spectroscopy of rare-earth orthoferrites RFeO3 (R = La, Sm, Eu, Gd, Tb, Dy)
Mads Christof Weber, Mael Guennou, Hong Jian Zhao +5
We report a Raman scattering study of six rare earth orthoferrites RFeO3, with R = La, Sm, Eu, Gd, Tb, Dy. The use of extensive polarized Raman scattering of SmFeO3 and first-princ…
