Every time a new Hall effect is discovered, a wave of research is inspired. The first experiment on a new type of Hall effect, the layer Hall effect, had been reported by Xu's group at Harvard University. In the layer Hall effect, electrons from the top and bottom layers are deflected in opposite directions and were measured by applying an out-of-plane electric field to break the PT symmetry, where P and T represent inversion symmetry and time-reversal symmetry, respectively.
