Semiconducting self-assembled liquid crystals

Niels Bohr Institute Lecture by Maxim Shkunov, Advanced Technology Institute, School of Electronics and Physical Sciences, University of Surrey Guildford, UK.

Abstract
Nature mastered self-assembly for millions of years in various forms ranging from extra strong spider silk to iridescent butterfly wings.We are just starting to benefit from basic understanding of these self-organisation mechanisms to advance man-made materials and devices.Liquid crystalline semiconductor ordering and chemical self-assembly techniques present outstanding opportunities for a development of large-area electronic applications including flexible displays, disposable sensors, smart electronic tags and others. To achieve efficient charge transport, required in such applications, highly ordered molecular structures are obtained through alignment in thermotropic mesophases and then crosslinked to preserve the order.As a result, high, temperature independent mobility is measured in these supramolecular structures.
