Abstract

By employing a post-treatment in N2 atmosphere at room temperature, the electrical properties of ink-jet printed triisopropylsilyl pentacene organic thin-film transistors (OTFTs) such as current on/off ratio and subthreshold slope were significantly improved. The current on/off ratio of the OTFT device increased from 104 to 105 after the post-treatment and the subthreshold slope was improved from 8.5 V/decade to 2 V/decade. The field-effect mobility of the device was not significantly affected by the post-treatment. We have also employed a post-treatment in vacuum at room temperature and the off-current of OTFT devices decreased by 1 order after the treatment.
