Until recently subwavelength optics laid great hopes on the effects related to interactions of light with the, so-called, plasmons -- collective oscillations of free electron gas in metals.
The electrons harbored at the interface form a sheet of charges, called two-dimensional electron gas.

To make measurements of electronic flow, some researchers have forced an electron gas to pass through a narrow, electrically defined gap, before permitting the electrons to spread out again.
Some of the electrons in the gold are not anchored to individual atoms but instead form a free-floating electron gas, explained Xia.
