TL;DR: It is demonstrated that high-quality, few-layer BP nanosheets, with controllable size and observable photoluminescence, can be produced in large quantities by liquid phase exfoliation under ambient conditions in solvents such as N-cyclohexyl-2-pyrrolidone (CHP).
Journal ArticleDOI
Sample preparation for atomic-resolution STEM at low voltages by FIB.
TL;DR: All sample preparation has been carried out in modern Dual-Beam FIB microscopes capable of low-kV Ga(+) ion milling, but without additional preparation steps after the FIB lift-out procedure.
Journal ArticleDOI
Interface Ferromagnetism and Orbital Reconstruction in BiFeO3-La0.7Sr0.3MnO3 Heterostructures
Pu Yu,Jongmin Lee,Satoshi Okamoto,Marta D. Rossell,Mark Huijben,Mark Huijben,Chan-Ho Yang,Qing He,Jinxing Zhang,S. Y. Yang,M. J. Lee,Quentin M. Ramasse,Rolf Erni,Ying-Hao Chu,Dario Arena,Chi-Chang Kao,Lane W. Martin,Lane W. Martin,Ramamoorthy Ramesh,Ramamoorthy Ramesh +19 more
TL;DR: Using x-ray magnetic circular dichroism at Mn and Fe L(2,3) edges, it is discovered that the development of this ferromagnetic spin structure is strongly associated with the onset of a significant exchange bias.
Journal ArticleDOI

TL;DR: The instrument's new capabilities were exploited to detect a buried Σ3 {112} grain boundary and observe the dynamic arrangements of single atoms and atom pairs with sub-angstrom resolution, an important step toward meeting the challenge of determining the three-dimensional atomic-scale structure of nanomaterials.
Journal ArticleDOI
