Revealing buried ferroelectric topologies by depth-resolved electron diffraction imaging
Ting-Ran Liu, Koushik Jagadish, Xiangwei Guo +10
Nanoscale topological polar textures promise new functionalities for ferroelectric memories and logic, yet their three-dimensional structure and mesoscale organization remain exper…
Spatially modulated morphotropic phase boundaries in a compressively strained multiferroic thin film
Ting-Ran Liu, Xiangwei Guo, Sajid Husain +5
The coexisting rhombohedral-like (R', MA) and tetragonal-like (T', MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and…
Kinetic control of ferroelectricity in ultrathin epitaxial Barium Titanate capacitors
Harish Kumarasubramanian, Prasanna Venkat Ravindran, Ting-Ran Liu +11
Ferroelectricity is characterized by the presence of spontaneous and switchable macroscopic polarization. Scaling limits of ferroelectricity have been of both fundamental and techn…
Infrared Optical Anisotropy in Quasi-1D Hexagonal Chalcogenide BaTiSe3
Boyang Zhao, Hongyan Mei, Zhengyu Du +9
Polarimetric infrared detection bolsters IR thermography by leveraging the polarization of light. Optical anisotropy, i.e., birefringence and dichroism, can be leveraged to achieve…
