This document summarizes the quantum Hall effect. It describes the conditions needed to observe the effect including low temperatures, strong magnetic fields, and using a MOSFET. The quantum Hall effect results in the Hall resistivity being quantized as integers or fractions of h/e^2 depending on if it is the integer or fractional quantum Hall effect. The integer effect can be explained by considering non-interacting electrons forming discrete Landau levels. The fractional effect involves strongly interacting electrons condensing into an incompressible liquid state where quasiparticles have fractional charge.
