文摘

A range of proposed devices relies on the electronic, optical or magnetic properties of one-dimensional (1D) chains of nanoparticles. Here,well-controlled 1D arrays have been formed by templating a spherical-morphology block copolymer within a narrow groove. Significantly, thedomains are distorted into ellipses with aspect ratio and major axis orientation controlled by the groove width. This technique gives unprecedentedcontrol over the period, particle size, aspect ratio, and orientation of nanoparticles in 1D arrays, making it valuable for creating self-assembledmasks for the fabrication of novel devices.
