The Classical Hall Effect We usually plot the resistivity matrix Although it’s not directly relevant for our story, it’s worth pausing to think about how we actually approach equilibrium in the Hall e↵ect. We start by putting an electric field in the x-direction. This gives rise to a current density Jx, but this current is deflected

The quantum Hall effect (or integer quantum Hall effect) is a quantized version of the Hall effect which is observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, in which the Hall resistance R xy exhibits steps that take on the quantized values = =, where V Hall is the Hall voltage, I channel is the channel current, e …Quantum Hall Effects.
