Hall effect conductivity
WebAn Introduction to the Quantum Hall Effect Thomas DeMastri (Dated: December 2024) In this paper, the Hall Effect, Integer Quantum Hall (IQH) Effect, and Fractional Quantum Hall (FQH) Effect are discussed. The Hall Effect is explained in terms of the Drude Model of metals and IQH states through a band structure of non-interacting electrons.
