Splitting crystals for 2-D metallic conductivity
(PHYSorg.com Nanotechnology)

Sheets of electrons that are highly mobile in only two dimensions, known as 2-D electron gas, have unique properties that can be leveraged for faster and novel electronic devices. Researchers have been exploring 2-D electron gas, which was only discovered in 2004, to see how it can be used in superconductors, actuators and electronic memory devices, among others.
