Origin of Anomalous Size Effects in Ferroelectric Hafnia Thin Films
Tianyuan Zhu, Jingxuan Li, Zuhuang Chen +1
The persistence of ferroelectricity in ultrathin HfO films challenges conventional theories, particularly given the paradoxical observation that the out-of-plane lattice spacin…
Multiferroic VHfO with Strain-Tunable Magnetism
Qisheng Yu, Tianyuan Zhu, Boyu Liu +2
The coexistence of ferroelectricity and magnetism in a single-phase oxide is rare because the electronic requirements for these two orders are often incompatible. Here, using first…
Unexpected Density Functional Dependence of the Antipolar Phase in HfO
Di Fan, Tianyuan Zhu, Shi Liu
The antipolar phase of HfO has been suggested to play an important role in the phase transition and polarization switching mechanisms in ferroelectric hafnia. In this st…
Origin of Interstitial Doping Induced Coercive Field Reduction in Ferroelectric Hafnia
Tianyuan Zhu, Liyang Ma, Xu Duan +1
Hafnia-based ferroelectrics hold promise for nonvolatile ferroelectric memory devices. However, the high coercive field required for polarization switching remains a prime obstacle…
Progress in Computational Understanding of Ferroelectric Mechanisms in HfO
Tianyuan Zhu, Liyang Ma, Shiqing Deng +1
Since the first report of ferroelectricity in nanoscale HfO-based thin films in 2011, this silicon-compatible binary oxide has quickly garnered intense interest in academia and…
Intrinsic ferroelectric switching in two-dimension -InSe
Liyi Bai, Changming Ke, Zhongshen Luo +3
Two-dimensional (2D) ferroelectric semiconductors present opportunities for integrating ferroelectrics into high-density ultrathin nanoelectronics. Among the few synthesized 2D fer…
