Nanorings Could Hold Key to Faster Computers
Researchers at The Johns Hopkins University have discovered that asymmetrical â€śnanoringsâ€ť â€”tiny, irregularly shaped nickel or cobalt ringsâ€”can 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.
