Integer Quantum Hall Effect: Disorder, temperature, floating, and plateau width
Stuart Yi-Thomas, Yi Huang, Jay D. Sau +1
We theoretically consider disorder and temperature effects on the integer quantum Hall effect (IQHE) using a variety of distinct and complementary analytical and numerical techniqu…
