Nano-scale visualization of magnetic vortices in metal nanoparticles
Satoko Toyama, Yoshiki O. Murakami, Ayako Nishikawa +4
Magnetic vortices in individual nanoparticles are fundamental spin structures that govern the properties of next-generation magnetic devices and biomedical applications. However, d…
Metallic NbS2 one-dimensional van der Waals heterostructures
Wanyu Dai, Yongjia Zheng, Akihito Kumamoto +12
This study presents the experimental realization of metallic NbS2-based one-dimensional van der Waals heterostructures applying a modified NaCl-assisted chemical vapor deposition a…
One-dimensional van der Waals Heterostructures: Growth Mechanism and Handedness Correlation Revealed by Non-destructive TEM
Yongjia Zheng, Akihito Kumamoto, Kaoru Hisama +15
In this work, we perform a follow-up and comprehensive study on the structural details and formation mechanism of chemical vapor deposition (CVD) synthesized one-dimensional (1D) v…
One-dimensional van der Waals heterostructures
Rong Xiang, Taiki Inoue, Yongjia Zheng +23
Property by design is one appealing idea in material synthesis but hard to achieve in practice. A recent successful example is the demonstration of van der Waals (vdW) heterostruct…
Atomic-Scale Structure Relaxation, Chemistry and Charge Distribution of Dislocation Cores in SrTiO3
Peng Gao, Ryo Ishikawa, Bin Feng +3
By using the state-of-the-art microscopy and spectroscopy in aberration-corrected scanning transmission electron microscopes, we determine the atomic arrangements, occupancy, eleme…
Picometer-scale atom position analysis in annular bright-field STEM imaging
Peng Gao, Akihito Kumamoto, Ryo Ishikawa +3
We study the effects of specimen mistilt on the picometer-scale measurement of local structure by combing experiment and simulation in annular bright-field scanning transmission el…
