Evaluation on thin film organic field effect transistors for sensing applications

A new technology for sensing LPG by combining the properties of GFET, Graphene and HBN is reported in this work. It is reported that the use of organic semiconductor material can decrease the cost of the sensor substantially. The limited carrier mobility of OFET is improved by the addition of Graphene and HBN. Pentacene is also used in the expectation of enhancing carrier transport capabilities. An added advantage is that the same sensor can be used for the selective detection of sulphur dioxide and n-butane.
