Description

General description

2-Mercapto-5-nitrobenzimidazole (MNB) is a charge transfer molecule and its influence on SiO₂ and Au electrode on pentacene organic thin film transistors has been investigated. The treatment of the Au electrodes of an organic bottom-contact thin film transistor with MNB, improves the current-voltage characteristics.
