Postdoc with External Senior Fellow Ullrich Steiner
Ed Crossland studied Natural Sciences at the University of Cambridge and received his Master of Science degree in Physics in 2002 for which he was awarded the Caldwell Scholarship by Corpus Christi College, Cambridge. He spent a year travelling the world; stopping to learn Spanish in South America and to study computational fluid dynamics with Prof. Paul Callaghan in the MacDiarmid Institute for Advanced Materials and Nanotechnology, Victoria University of Wellington, NZ. In 2003 he returned to London and worked as an analyst for Latitude LLP business strategy consultancy. He joined the Cavendish Laboratories and Cambridge Nanoscience Centre in 2004 where he completed his PhD research developing hybrid solar cells made from highly ordered semiconductor mesostructures patterned using molecular self assembly of block copolymers. In 2008 he became a Junior Research Fellow in the School for Soft Matter Research at FRIAS.
Molecular order and electronic charge transport in semi-crystalline polymers
The impressive optoelectronic performance and technological potential of many conjugated polymer semiconductors arises rather directly from their ability to crystallize. The passage of electronic charge in particular depends crucially on exactly how the polymer chains are allowed to assemble. We aim to carefully direct specific features of polymer crystal morphology and correlate these to the critical factors determining charge transport along different molecular directions. We also investigate the modified self assembly and charge transport characteristics of rod-coil semiconducting block copolymers.
