Thickness-Driven Superconductor-Insulator Transition in (Cu,C)-1234 and Proximity-Induced Superconductivity Recovery in (Cu,C)-1234/YBCO Heterostructure
Zhihang Xu, Detian Yang, Ping Zhu +4
Superconducting proximity effect and related thickness-driven property evolution remain an important issue in understanding high temperature superconductors. Among proximity system…
Billion-Fold Enhancement of Room-Temperature Ionic Conductivity in h-RMnO3/YSZ Heterostructures via Electric-Field-Assisted Oxygen Deficiency Engineering
Detian Yang, Yaohua Liu, Liang Dai +2
Oxide heterostructures provide versatile platforms for manipulating electronic and ionic conductive states. In this study, we demonstrate a remarkable billion-fold enhancement in r…
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 Exchange Bias from Interfacial Reconstruction in an Epitaxial NixCoyFe3-x-yO4(111)/α-Al2O3(0001) Thin Film Family
Detian Yang, Yaohua Liu, Xiaoshan Xu
Intrinsic exchange bias is known as the unidirectional exchange anisotropy that emerges in a nominally single-component ferro-(ferri-)magnetic system. In this work, with magnetic a…
Enhance Ferroelectric Structural Distortion via Doping Ca in Epitaxial h-Lu1-xCaxMnO3 Thin Films
Detian Yang, Yaohua Liu, Xiaoshan Xu
Unlike proper ferroelectricity, the improper ferroelectricity in multiferroic rare-earth manganites h-ReMnO3 (Re=La-Lu,Y,Sc) thin films features a unique geometric distortion and s…
