Reversible metal-insulator transition in LaAlO 3 thin films mediated by intragap defects: An alternative mechanism for resistive switching
Zhiqi Liu,D. P. Leusink,W. M. Lü,X.P. Wang,Xuefeng Yang,Kalon Gopinadhan,Y. T. Lin,Anil Annadi,Y. L. Zhao,A. Roy Barman,Sankar Dhar,Yuan Ping Feng,Haibin Su,G. Xiong,Thirumalai Venkatesan,Ariando +15 more
TL;DR: In this paper, the authors reported on the electric field-induced reversible metal-insulator transition (MIT) of the insulating LaAlO{}_{3}$ thin films observed in metal/LaAlO${}{ 3}$/Nb-SrTiO{ 3]$ heterostructures.
Journal ArticleDOI
Growth of carbon nanotube arrays using the existing array as a substrate and their Raman characterization
Lianfeng Sun,Lianfeng Sun,Zhiqi Liu,X.C. Ma,Ziyi Zhong,S.B. Tang,Zhitao Xiong,Dongsheng Tang,W.Y. Zhou,X. P. Zou,Y.B. Li,K. L. Tan,Shuhong Xie,Jianyi Lin +13 more
TL;DR: In this article, the authors report that after oxidation in air and reduction in hydrogen, the existing carbon nanotube arrays can be used as a substrate to grow another nanotub array.
Journal ArticleDOI
Long-range magnetic coupling across a polar insulating layer.
W. M. Lü,Surajit Saha,X. Renshaw Wang,Zhiqi Liu,Kalon Gopinadhan,Anil Annadi,Shengwei Zeng,Zhen Huang,B. C. Bao,Chunxiao Cong,Munuswamy Venkatesan,Ting Yu,J. M. D. Coey,J. M. D. Coey,Ariando,Thirumalai Venkatesan +15 more
TL;DR: A magnetic interaction that can propagate over long distances (∼10 nm) across a polar insulating oxide spacer is reported, which raises the prospect of terahertz tunability of magnetic coupling.
Journal ArticleDOI
Frontiers in strain-engineered multifunctional ferroic materials
Joshua C. Agar,Shishir Pandya,Ruijuan Xu,Ajay K. Yadav,Zhiqi Liu,Thomas Angsten,Sahar Saremi,Mark Asta,Mark Asta,Ramamoorthy Ramesh,Lane W. Martin,Lane W. Martin +11 more
TL;DR: In this article, the authors highlight important developments in theoretical and computational techniques, materials synthesis, and characterization techniques, and explore how these new approaches could revolutionize our ability to discover, probe, and engineer these materials and provide a context for new arenas where these materials might make an impact.
Journal ArticleDOI
Bandgap Controlling of the Oxygen-Vacancy-Induced Two-Dimensional Electron Gas in SrTiO3
Zhiqi Liu,W. M. Lü,Shengwei Zeng,J. W. Deng,Zhen Huang,Changjian Li,Mallikarjuna Rao Motapothula,W. M. Lü,Lianfeng Sun,Kun Han,Jian-Qiang Zhong,Ping Yang,Nina Bao,Wei Chen,Jingsheng Chen,Yuan Ping Feng,J. M. D. Coey,T. Venkatesan,Ariando +18 more
TL;DR: In this paper, the authors reported very large bandgap enhancement in SrTiO3 (STO) films, which can be up to 20% greater than the bulk value, depending on the deposition temperature.
