Theoretical physicists reveal how twisting layers of material creates mysterious electron path deflection effects

(Left) Atomic force microscopy image showing a sample of twisted layers of WS2 (a material made of tungsten and sulfur). Scale bar represents 4 micrometers (4 millionths of a meter). (Right) Diagram showing how to measure the Hall effect (lateral voltage) in twisted materials. The red arrow represents the path of the electron, and V0 and VH are the voltages…
