Nature:
Electrons confined to the interface between two semiconductors
form what is known as a two-dimensional electron gas -
essentially, a two-dimensional metal. These materials provide a
playground for the exploration of fundamental physics. Writing
in Physical Review Letters, M. A. Zudov, R. R. Du, L. N.
Pfeiffer, and K. W. West describe a experiment designed to shed
light on one such phenomenon: 'zero-resistance' states induced
by the application of a magnetic field and microwave radiation.
