The electrical resistivity of the AZO films with a 180-nm thickness was 4.085 x 10(-2) Omega cm, and the average optical transmittance in the visible range was 80.2%. The surface work function for the AZO films, determined from the secondary electron emission coefficients obtained with a focused ion beam, was as high as 4.62 eV. These results indicate that AZO films grown on glass substrates hold promise for potential applications as anode electrodes in high-efficiency OLEDs. (c) 2006 Elsevier B.V. All rights reserved.
