Two-Dimensional Electron Gas (2DEG) - overview


Physics Accomplishment | 1966

IBM researchers: Alan B. Fowler Frank F. Fang, Webster E. Howard and Phillip J. Stiles

Where the work was done: IBM T.J. Watson Research Center

What we accomplished: The demonstration of surface quantization (the 2DEG) at the interface between silicon and silicon dioxide by Fowler, Fang, Howard and Stiles has had an ever broadening impact in condensed matter physics. This was the first demonstration that clean quantization could occur in a solid state system.

2DEG has since been observed in many other materials  systems and structures. It is now seen as the original example of an electronic system of reduced dimensionality, and such systems have many important technological applications. This physics enabled many important practical applications, including the semiconductor quantum dots used to brighten the colors produced by your flat screen TV, and the ability to adjust the color spectrum of LED light bulbs.
