Scientists say they've gone where nanotech researchers never have, and the result makes futuristic IT and electronics that much more likely.
Researchers say they have fabricated ultra-small wires out of materials that could previously never be used together. The result, they say, represents a major advance in nanotechnology research, and could move the sci-fi fantasy of ultra-small supercomputers and microscopic electronic devices closer to reality.
University of California-Berkeley chemist Peidong Yang says he made "superlattice" nanowire, a strand less than 100 nanometers in diameter, by alternating segments of silicon and silicon germanium. Yang "grew" the wire like a crystal, adding blocks of each material in turn as the structure formed.
"These are not materials you can bring together in a traditional semiconductor manufacturing environment," says Larry Bock, president and CEO of Nanosys Inc., a company he co-founded with Yang which is licensing the technology. "But when you operate down on this size scale, you don't have those surface tensions."
The result combines the best of both materials, and its composition can be customized for different functions. A nano-wire can precisely control electrical current, can emit light, can heat or cool a device, or even store information. And the tiny wires can serve as components for more complicated devices, allowing engineers to build smaller and smaller electronic and optical hardware.
5 Top Federal Initiatives For 2015As InformationWeek Government readers were busy firming up their fiscal year 2015 budgets, we asked them to rate more than 30 IT initiatives in terms of importance and current leadership focus. No surprise, among more than 30 options, security is No. 1. After that, things get less predictable.
Top IT Trends to Watch in Financial ServicesIT pros at banks, investment houses, insurance companies, and other financial services organizations are focused on a range of issues, from peer-to-peer lending to cybersecurity to performance, agility, and compliance. It all matters.
