Theoretical physicist uncovers how twisting layers of a material can generate a mysterious electron-path-deflecting effect

Phys.org  October 4, 2024 Studies of moiré systems have explained the effect of superlattice modulations on their properties, demonstrating new correlated phases. However, most experimental studies have focused on a few layers in two-dimensional systems. Extending twistronics to three dimensions, in which the twist extends into the third dimension, remains underexplored because of the challenges associated with the manual stacking of layers. A team of researchers in the US (University of Pennsylvania, SLAC National Accelerator Laboratory, University of Wisconsin-Madison) studied three-dimensional twistronics using a self-assembled twisted spiral superlattice of multilayered WS2. Their findings showed an opto-twistronic Hall effect driven by […]
