Using laser light to tune electronic energy levels

Using laser light to tune electronic energy levels


Researchers at the Massachusetts Institute of Technology have discovered a new way of using laser light to tune electronic energy levels in 2D films of crystal.

More about this image
Faster, more efficient data storage and computer logic systems could be on the horizon thanks to a new way of tuning electronic energy levels in 2D films of crystal, discovered by researchers at the Massachusetts Institute of Technology (MIT). The discovery could ultimately pave the way for the development of so-called "valleytronic" devices, which harness the way electrons gather around two equal energy states, known as valleys.

Learn more about this discovery in the MIT news story Toward 'valleytronic' devices for data storage or computer logic systems. [Note: See "Restrictions" below regarding use of this image.] (Date image taken: unknown; date originally posted to NSF Multimedia Gallery: Dec. 11, 2018)
