WebSep 10, 2009 · Chapter 3 is devoted to the transport characteristics of the integer quantum Hall effect, and the basic aspects of the fractional quantum Hall effect are described in chapter 4. In chapter 5, we briefly discuss several multicomponent quantum Hall systems, namely the quantum Hall ferromagnetism, bilayer systems and graphene that may be … WebThis effect is called integer quantum Hall effect. Interestingly, the values of the Hall resistance are independent on the materials chosen in the measurements. Figure 2: Model for the broadened density of states of a 2DEG in a strong magnetic field. Mobility edges close to the center of the Landau levels separate extended states
