Superior Photo-carrier Diffusion Dynamics in Organic-inorganic Hybrid Perovskites Revealed by Spatiotemporal Conductivity Imaging
Xuejian Ma, Fei Zhang, Zhaodong Chu +9
The outstanding performance of organic-inorganic metal trihalide solar cells benefits from the exceptional photo-physical properties of both electrons and holes in the material. He…
Nanoscale Conductivity Imaging of Correlated Electronic States in WSe2/WS2 Moiré Superlattices
Zhaodong Chu, Emma C Regan, Xuejian Ma +10
We report the nanoscale conductivity imaging of correlated electronic states in angle-aligned WSe2/WS2 heterostructures using microwave impedance microscopy. The noncontact microwa…
Unveiling Defect-Mediated Carrier Dynamics in Monolayer Semiconductors by Spatiotemporal Microwave Imaging
Zhaodong Chu, Chun-Yuan Wang, Jiamin Quan +13
The optoelectronic properties of atomically thin transition-metal dichalcogenides are strongly correlated with the presence of defects in the materials, which are not necessarily d…
Visualization of Local Conductance in MoS2/WSe2 Heterostructure Transistors
Di Wu, Wei Li, Amritesh Rai +7
The vertical stacking of van der Waals (vdW) materials introduces a new degree of freedom to the research of two-dimensional (2D) systems. The interlayer coupling strongly influenc…
Energy-resolved Photoconductivity Mapping in a Monolayer-bilayer WSe2 Lateral Heterostructure
Zhaodong Chu, Ali Han, Chao Lei +10
Vertical and lateral heterostructures of van der Waals materials provide tremendous flexibility for band structure engineering. Since electronic bands are sensitively affected by d…
Correlation between Dzyaloshinskii Moriya interaction and spin mixing conductance at antiferromagnet / ferromagnet interface
Xin Ma, Guoqiang Yu, Seyed A. Razavi +6
The rich interaction phenomena at antiferromagnet (AFM)/ ferromagnet (FM) interfaces are key ingredients in AFM spintronics, where many underlying mechanisms remain unclear. Here w…
