Block copolymer thin films are effective templates for fabricating large arrays of nanoscopic objects; for example, polymers which self-assemble into cylinders lying in the plane of the film yield striped patterns, which can be replicated in metal to yield nanowire grids which effectively polarize the short-wavelength

Thin block copolymer films are highly relevant for many scientific and industrial applications due to their ability to form uniform domains of controllable shape at nanometer length scales.
We investigated the electronic properties of interfaces between two laminated polymer films. The top polymer film (Fig. (a)) is transferred to a soft PDMS stamp, and laminated against the bottom film, previously spin-coated on a substrate.
Studying the electronic properties of the surface states on Topological Insulators requires high quality bulk crystals. We have figured out the defect chemistry of these compounds and grown crystals by the Bridgman Stockbarger method.
Artists and material scientists alike bend, melt and mold materials into useful and aesthetically pleasing forms. But nothing human hands have made can match the intricacy of convoluted corals or the delicate and unique geometry of a snowflake.
