Paper ready for go



The closing work from my time at the Cavendish is ready for publication. Henning has been kind enough to do a bit of the polishing for me which is nice. So I have been busy the last few days putting the figures into their final configuration and getting all of the references ready. This here is figure one. the part a) shows the molecular sturcture of the pBTTT molecule emphasising that the side chains like to interdigitate, which allows it to become much more crystalline than some other polymers. The part b) shows a schematic of the ribbons that this polymer self assembles into. the ribbons are made of lots of the molecules stacked up. But intebween the ribbons there are faults in the crystal structure. These faults allow for the trapping of positive charges called holes. The paper then goes on to show that we can actually use SKPM to view the holes and the watche them slowly detrap. So, I am happy with the paper. Now I am going to give it a final read over and send it off to the co-authors to get their okay.
