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…
Imaging Polarity in Two Dimensional Materials by Breaking Friedel's Law
Pratiti Deb, Michael C. Cao, Yimo Han +5
Friedel's law guarantees an inversion-symmetric diffraction pattern for thin, light materials where a kinematic approximation or a single-scattering model holds. Typically, breakin…
Scaling-up atomically thin coplanar semiconductor-metal circuitry via phase engineered chemical assembly
Xiaolong Xu, Shuai Liu, Bo Han +11
Two-dimensional (2D) layered semiconductors, with their ultimate atomic thickness, have shown promise to scale down transistors for modern integrated circuitry. However, the electr…
Tailoring Semiconductor Lateral Multi-junctions for Giant Photoconductivity Enhancement
Yutsung Tsai, Zhaodong Chu, Yimo Han +9
Semiconductor heterostructures have played a critical role as the enabler for new science and technology. The emergence of transition metal dichalcogenides (TMDs) as atomically thi…
Coherent Atomically-Thin Superlattices with Engineered Strain
Saien Xie, Lijie Tu, Yimo Han +7
Epitaxy forms the basis of modern electronics and optoelectronics. We report coherent atomically-thin superlattices, in which different transition metal dichalcogenide monolayers--…
Sub-Nanometer Channels Embedded in Two-Dimensional Materials
Yimo Han, Ming-Yang Li, Gang-Seob Jung +5
Two-dimensional (2D) materials are among the most promising candidates for next-generation electronics due to their atomic thinness, allowing for flexible transparent electronics a…
