Abstract
This article describes an anthracene derivative nitropyridine conjugated (NC) substituent has been efficiently used in Schottky junction applications. The effect of solution aging with a long period from 1h 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 0.860eV, 0.710 to 0.884eV, 0.715 to 0.836eV and 0.678 to 0.683eV 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.
