Abstract:

Ultrathin diblock copolymer films have been offered as promising candidates for bottom-up templates in nanotechnological applications. Their natural tendency to self-organize into laterally alternating domains with a length scale tunable in the range of 10-100 nm is fundamental to their potential in this arena. However, having arbitrary control over the orientation of these domains is equally crucial and, until now, largely unrealized. We will present a novel lithographically assisted self-assembly approach that leads to low defect density domains of mesoscopic dimensions spanning 0.2-2 micrometer in width, 100 micrometer in length, and with nanoscopic features down to 20 nm. Potential applications extend from fundamental polymer science to sensor technology, electronicsspintronics, and optics.
