Humidity sensor using a single molecular transistor

Abstract

Nanoelectronic devices have attracted significant interest for their potential as chemical/gas sensors. In this work, the performance and operation of a novel single molecular transistor based humidity sensor are demonstrated for the first time using density function theory based Ab-initio calculations. The device has a novel design, which can allow real-time detection through the charge stability diagram. It is found that this method can allow large temperature range of operation with extremely high detection sensitivity than the presently available sensors, while the simplistic design can be useful for practical experimental realisation.
