Theory of Hall effect in two-dimensional giant Rashba systems

A Hall effect sensor (or simply Hall sensor) is a type of sensor which detects the presence and magnitude of a magnetic field using the Hall effect. The output voltage of a Hall sensor is directly proportional to the strength of the field. It is named for the American physicist Edwin Hall. Hall sensors are used for proximity sensing, positioning, speed detection, and cu… WebbThe FQHE is a manifestation of correlation effects among the charge carriers interacting in the two-dimensional system, which lead to the formation of new quantum states.
