Abstract
The two complexes Ru(II) containing 2,6-bis(benzimidazol-2-yl)pyridine and 2-pyridine and 2-quinoline carboxylates were synthesized to fabricate organic photodiodes. The electrical properties of Au/Ru(II) complex (I)/n−Si/Al and Au/Ru(II)complex (II)/n−Si/Al diodes were investigated by current-voltage and capacitance-voltage measurements. The fabricated devices give a high rectification behavior with rectification ratio of 2.4 ×104 −2.1 ×103 at ±4 V. The diodes exhibited a high photoconductivity based on trap levels within band gap. The series resistance and barrier height were calculated from (C−V) measurements and compared to other of (I−V). The obtained results indicate that the prepared photodiodes can be used as photosensor for optoelectronic applications. © 2017
