Antiferroelectric Hafnia Down to the 2D Limit
Xin Li, Guodong Ren, Haidong Lu +16
Antiferroelectricity is a material property characterized by alternating electric dipoles spontaneously ordered in antiparallel directions. Antiferroelectrics are promising for ene…
Dual mechanisms for transient capacitance anomaly in improper ferroelectrics
Xin Li, Yu Yun, Pratyush Buragohain +6
The recent discovery of transient negative capacitance has sparked an intense debate on the role of homogeneous and inhomogeneous mechanisms in polarizations switching. In this wor…
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…
Imaging Local Effects of Voltage and Boron Doping on Spin Reversal in Antiferromagnetic Magnetoelectric Cr2O3 Thin Films and Devices
Adam Erickson, Syed Qamar Abbas Shah, Ather Mahmood +5
Chromia (Cr2O3) is a magnetoelectric oxide which permits voltage-control of the antiferromagnetic (AFM) order, but it suffers technological constraints due to its low Neel Temperat…
