30 August 2012—Researchers at Cornell University, in Ithaca, N.Y., are doing work that suggests electronic circuits could continue to be miniaturized until they are just a few nanometers thick. The Cornell team reports in this week’s Nature that it has developed a technique for manufacturing the components of electronic circuits on a single one-atom-thick sheet. The result, they say, will be flexible and transparent electronics that are as thin as they can possibly be. Stacking these sheets could someday yield complex, three-dimensional integrated circuits that are still slimmer than any of today’s chips.

Seventy-five years is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.
