Millimeter-Scale, Atomically Controlled 2D Topological Insulators Revealed by Multimodal Spectroscopy

Abstract Quantum spin Hall insulators, also known as 2D topological insulators, are crucial 2D systems hosting topologically protected edge states. The working temperature of this topological quantum phase is dictated by the inverted bandgap. However, the previously identified la...

Chirality-Induced One-Way Magnetoresistance in Gold Nanocrystals

Abstract Magnetoresistance (MR), a cornerstone for quantum materials and quantum devices, is usually symmetric (sometimes antisymmetric) under magnetic field reversal. Here, we report a chirality-induced one-way magnetoresistance (ChiMR) in gold nanocrystals, where MR is strongly...
