Quantum conductors in a plane [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
When electrons are confined to move in a plane, strange things happen. For example, under normal circumstances, they are not expected to conduct electricity at low temperatures. However, recent experiments on a dilute electron gas confined to move at the interface between two semiconductors pose a distinct counterexample to the standard view. Transport
