Millimeter-Scale, Atomically Controlled 2D Topological Insulators Revealed by Multimodal Spectroscopy
Woojoo Lee, Qiang Gao, Yufei Zhao +20
Quantum spin Hall insulators, or synonymously known as 2D topological insulators, are crucial 2D systems hosting topologically protected edge states. The working temperature of thi…
Crossover Dynamics of Non-Fickian Ionic Diffusion in Solids
Gangbin Yan, Pierfrancesco Ombrini, Zhichu Tang +14
Ionic diffusion in solids is central to energy storage, electronics, and catalysis, yet its chemical origins are difficult to resolve because conventional diffusion models struggle…
A Topological Superconductor Tuned by Electronic Correlations
Haoran Lin, Christopher L. Jacobs, Chenhui Yan +15
A topological superconductor, characterized by either a chiral order parameter or a chiral topological surface state in proximity to bulk superconductivity, is foundational to topo…
Cooperative and Inhibitory Ion Transport in Functionalized Angstrom-Scale Two-Dimensional Channels
Mingzhan Wang, Qinsi Xiong, Gangbin Yan +12
Significant success has been achieved in fabricating angstrom-scale artificial solid ionic channels aiming to replicate the biological ion channels (BICs).Besides high selectivity,…
Preservation of Topological Surface States in Millimeter-Scale Transferred Membranes
Chi Ian Jess Ip, Qiang Gao, Khanhy Du Nguyen +10
Ultrathin topological insulator membranes are building blocks of exotic quantum matter. However, traditional epitaxy of these materials does not facilitate stacking in arbitrary or…
