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…
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…
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…
Intrinsic ferroelectricity in Y-doped HfO2 thin films
Yu Yun, Pratyush Buragohain, Ming Li +10
Ferroelectric HfO2-based materials hold great potential for widespread integration of ferroelectricity into modern electronics due to their robust ferroelectric properties at the n…
Piezoelectricity in hafnia
Sangita Dutta, Pratyush Buragohain, Sebastjan Glinsek +7
Because of its compatibility with semiconductor-based technologies, hafnia (HfO) is today's most promising ferroelectric material for applications in electronics. Yet, knowle…
Persistent Ionic Photo-responses and Frank-Condon Mechanism in Proton-transfer Ferroelectrics
Xuanyuan Jiang, Xiao Wang, Pratyush Buragohain +8
Photoexcitation is well-known to trigger electronic metastable states and lead to phenomena like long-lived photoluminescence and photoconductivity. In contrast, persistent photo-r…
