| dc.description.abstract | This work concerns the microsctructure of benzimidazobenzophenanthroline, BBL, films doped with carbon nanotubes, CNTs, to increase the electron mobility of the films. The CNT dopings were 1, 9 and 50 wt% respectively. The microsctructures were studied using electron microscopy including scanning electron microscopy and transmission electron microscopy. The morphology of the films gradually changed from a continuous BBL film with a relatively rough surface morphology in the 1 wt% films with randomly oriented CNTs to a structure with the BBL forming a smooth shell of BBL on the CNTs. The CNTs were multiwalled with a high density of defects. The thickness of the BBL shell was about 20-30 nm in the 1 and 9 wt% films and 3-4 nm in the 50 wt% films. The results show that the electron mobility can be even further increased by aligning the CNTs that have a considerably higher mobility along their long axis and also compared to the BBL. It should be noted that an alignment of the CNTs would also result in a high directional anisotropy of the mobility in the BBL:CNT films. | sv |
