Response diversity and dual response mechanism of organic field-effect transistors with dinitrotoluene vapor

Abstract

We employ an assortment of n- and p-channel organic semiconductors to fabricate organic field-effect transistors (OFETs) that respond in different ways to dinitrotoluene (DNT) vapor. Different responses are obtained from devices with various semiconductor materials and receptor functionality. Differences are noted in the magnitude and direction of current changes, and also the device parameters (mobility and threshold voltage) affected. The pattern of responses includes sufficient diversity to set it apart from other vapors that might give similar responses to some OFETs in the set, but not all of them. This gives rise to the possibility of distinguishing DNT from other vapors in a manner that could be further developed using mechanistic principles elucidated in this work.
