= Semicircle law (quantum Hall effect)
{wiki=Semicircle_law_(quantum_Hall_effect)}
The semicircle law is a concept that arises in the context of the quantum Hall effect, particularly in relation to the energy spectrum of two-dimensional electron systems in strong magnetic fields. The quantum Hall effect itself is observed in a two-dimensional electron gas (2DEG) when subjected to low temperatures and strong magnetic fields, leading to quantized Hall conductance and unusual electronic behaviors.
