Özet

This article describes an anthracene derivative nitropyridine conjugated (N-C) substituent has been efficiently used in Schottky junction applications. The effect of solution aging with a long period from 1 h to 1 week on diode parameters such as ideality factor, barrier height, and series resistance were studied in details. The barrier height varied almost linearly with aging and the values increased from 0.623 to 0.860 eV, 0.710 to 0.884 eV, 0.715 to 0.836 eV and 0.678 to 0.683 eV determined from I-V method, Cheung's, Norde's functions and C-V method, respectively, on the other hand, the ideality factor decreased from 3.08 to 1.55 and 3.24 to 1.52 determined from I-V and Cheung functions respectively, with increase in aging. Low ideality factor suggests an ideal Schottky junction formation. The series resistance values obtained from Norde's function and Cheung functions exhibited a good agreement and a strong dependence to solution aging. (C) 2016 Elsevier Ltd. All rights reserved.
