Ying-Hao Chu,Q. Zhan,Chan-Ho Yang,M. P. Cruz,Lane W. Martin,T. Zhao,Pu Yu,Ramamoorthy Ramesh,P. T. Joseph,I-Nan Lin,Wei Tian,D. G. Schlom +11 more
TL;DR: In this paper, the role of La substitution on the ferroelectric properties of epitaxial BiFeO3 films on SrTiO3-templated Si was probed.
Journal ArticleDOI
Near-field examination of perovskite-based superlenses and superlens-enhanced probe-object coupling
Susanne C. Kehr,Susanne C. Kehr,Yongmin Liu,Lane W. Martin,Lane W. Martin,Pu Yu,M. Gajek,Sy Yang,Chan-Ho Yang,Chan-Ho Yang,Marc Tobias Wenzel,Rainer Jacob,H.-G. von Ribbeck,Manfred Helm,Xiang Zhang,Xiang Zhang,Lukas M. Eng,Ramamoorthy Ramesh,Ramamoorthy Ramesh +18 more
TL;DR: A superlens for electric evanescent fields with low losses using perovskites in the mid-infrared regime using near-field microscopy with a tunable free-electron laser to address precisely the polariton modes, which are critical for super-resolution imaging.
Journal ArticleDOI
High quality atomically thin PtSe 2 films grown by molecular beam epitaxy
Mingzhe Yan,Eryin Wang,Xue Zhou,Guangqi Zhang,Hongyun Zhang,Kenan Zhang,Wei Yao,Nianpeng Lu,Shuzhen Yang,Shilong Wu,Tomoki Yoshikawa,Koji Miyamoto,Taichi Okuda,Yang Wu,Pu Yu,Wenhui Duan,Shuyun Zhou +16 more
TL;DR: In this article, the first successful epitaxial growth of high quality PtSe2 films by molecular beam epitaxy was reported, which provides new opportunities for growing large size single crystalline films to investigate the physical properties and potential applications of PtSe 2.
Journal ArticleDOI
