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 […]
