Solid-state physics: Resistance is futile
Adam C. Durst1
Abstract
With the right combination of microwave radiation and magnetic field, two-dimensional electron systems conduct electricity with zero resistance. But is this zero really zero, or is it negative resistance in disguise?
Electrons confined to the interface between two semiconductors form what is known as a two-dimensional electron gas — essentially, a two-dimensional metal. Thanks to advances in semiconductor technology over the past few decades, two-dimensional electron gases of remarkably high purity can now be fabricated.
