Expanding Spin Memory (2 of 6)

Caption

Electrons (green arrows) flow through a silicon chip. Some are trapped in phosphorus donors (blue arrows). A donor can capture a second electron, leading to a decrease in current, only if the two electrons have opposite spin. This spin-trap was used to electrically read out the nuclear spin (red), where information is stored for over 100 seconds. This image relates to an article that appeared in the Dec. 17, 2010, issue of Science, published by AAAS. The study, by Dr. Dane R. McCamey at University of Utah in Salt Lake City, Utah, and colleagues was titled, "Electronic Spin Storage in an Electrically Readable Nuclear Spin Memory with a Lifetime >100 Seconds."
