Abstract

Organic diodes have been fabricated using 1,4,5,8-naphthalene-tetracarboxylic-dianhydride (NTCDA), poly(3,4-ethylenedioxythiophene) (PEDT), doped with poly(styrenesulfonate) (PSS) and polypyrrole (PPy) by simple and low-cost spin coating and thermal evaporation techniques. The current-voltage (I-V) characteristics have been investigated at room temperature, showing the breakdown voltages of about 9 V and the rectification ratios in excess of 4.1 × 103 for both NTCDA/PPy and NTCDA/(PEDT/PSS) diodes. The significant influence of acetone treatment on I-V characteristics is observed for NTCDA/PPy diodes.
