Automatic Parameter Selection for Electron Ptychography via Bayesian Optimization
Michael C. Cao, Zhen Chen, Yi Jiang +1
Electron ptychography provides new opportunities to resolve atomic structures with deep sub-angstrom spatial resolution and studying electron-beam sensitive materials with high dos…
A room temperature polar ferromagnetic metal
Hongrui Zhang, Yu-Tsun Shao, Rui Chen +15
The advent of long-range magnetic order in non-centrosymmetric compounds has stimulated interest in the possibility of exotic spin transport phenomena and topologically protected s…
Electron ptychography achieves atomic-resolution limits set by lattice vibrations
Zhen Chen, Yi Jiang, Yu-Tsun Shao +7
Transmission electron microscopes use electrons with wavelengths of a few picometers, potentially capable of imaging individual atoms in solids at a resolution ultimately set by th…
Structural Heterogeneity, Ductility, and Glass Forming Ability of Zr-Based Metallic Glasses
Soohyun Im, Pengyang Zhao, Geun Hee Yoo +9
We show the correlation between nanoscale structural heterogeneity and mechanical property and glass forming ability of Zr-based metallic glasses (MGs). Detailed parameters of medi…
Unusual Formation of Point Defect Complexes in the Ultra-wide Band Gap Semiconductor beta-Ga2O3
Jared M. Johnson, Zhen Chen, Joel B. Varley +10
Understanding the unique properties of ultra-wide band gap semiconductors requires detailed information about the exact nature of point defects and their role in determining the pr…
A polarization-induced 2D hole gas in undoped gallium nitride quantum wells
Reet Chaudhuri, Samuel James Bader, Zhen Chen +4
The long-missing polarization-induced two-dimensional hole gas is finally observed in undoped gallium nitride quantum wells. Experimental results provide unambiguous proof that a 2…
