Temperature-doping phase diagram and endurance in Ce-doped HfO2
Amit Kumar Shah, Haidong Lu, Kawshan Hathurusingha +2
The paper studies how adding cerium to ultrathin HfO2 films changes their crystal phases, ferroelectric polarization, and cycling endurance, establishing a temperature‑doping phase…
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…
Improper Ferroelectricity at the Monolayer Limit
Yilin Evan Li, Harikrishnan KP, Haidong Lu +20
Ultrathin ferroelectric films with out-of-plane polarization and high Curie temperatures are key to miniaturizing electronic devices. Most ferroelectrics employed in devices are pr…
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…
