|Abstract:||We investigate the electron-injecting properties of a ZnO substrate modified by a thin layer of solution-processed Cs2 CO3 into poly(9, 9′ -dioctylfluorene)-co-benzothiodiazole (F8BT). Ultraviolet photoemission spectroscopy studies reveal that in the case of coannealed F8BT/ Cs2 CO3 films, the Fermi level is pinned at the lowest unoccupied molecular orbital of the F8BT, indicating significant n-doping of the polymer. X-ray photoemission spectroscopy measurements reveal the presence of Cs2 CO3 in the coannealed F8BT/ Cs2 CO 3 films. I-V measurements in single carrier devices show a significant improvement in the electron injection of the coannealed F8BT/ Cs2 CO3, in agreement with the observed n-doping of the polymer upon coannealing. © 2011 American Institute of Physics.|
