Nanorings Could Hold Key to Faster Computers
Researchers at The Johns Hopkins University have discovered that asymmetrical ‚Äúnanorings‚ÄĚ ‚ÄĒtiny, irregularly shaped nickel or cobalt rings‚ÄĒcan serve as memory cells. Nanorings could be used to create a coin-sized hard drive for computers and bring advantages such as faster operating speeds and consuming much less energy. Doctoral candidates Frank Q. Zhu and Chia-Ling Chien discovered that the nanorings can store a large amount of information, and are resistant to the problem of stray magnetic fields. The production of asymmetrical nanorings would encompass multiple steps involving self-assembly, thin film deposition, and dry etching.
