Strain Forms Striped Nanorods
BERKELEY, Calif., July 23, 2007 -- Strain engineering, when applied to certain particles in a solution, spontaneously creates superlatticed or "striped" nanorods containing evenly spaced quantum dots, a research team has found. The approach is less expensive and exacting than current processes and suggests new uses for the crystalline materials, such as in tiny optoelectronic devices, LEDs and biological applications.
