Theory and Practice of Electron Diffraction from Single Atoms and Extended Objects using an Electron Microscope Pixel Array Detector
Michael C. Cao, Yimo Han, Zhen Chen +5
What does the diffraction pattern from a single atom look like? How does it differ from the scattering from long range potential? With the development of new high-dynamic range pix…
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…
Observation of oscillatory relaxation in the Sn-terminated surface of epitaxial rock-salt SnSe topological crystalline insulator
Wencan Jin, Suresh Vishwanath, Jianpeng Liu +20
Topological crystalline insulators have been recently predicted and observed in rock-salt structure SnSe thin films. Previous studies have suggested that the Se-terminate…
