New Application of Tunnel Junctions for Sensing Toxic and Explosive Gases
Abstract
This proposal aims to utilize large-area tunnel junctions formed with a microelectrode comprising liquid eutectic gallium-indium alloy (EGaIn) for sensing toxic and explosive gaseous molecules and offer the opportunity to demonstrate a new paradigm for developing an ultrasensitive detection system. The proposed research is important for both fundamental understanding of charge transport across organic matters, and developing a new detection platform based on ultrasensitivity of tunneling current density to structural variations of molecular component in junctions. The outcomes will be first scientifically focused, and then demonstrating strategies for fabricating practical electronic devices to sense the presence of gaseous analytes. It will provide a comprehensive set of data that demonstrate the responses of tunneling current densities to structural variations in molecules incorporated in junctions upon exposure to atmosphere containing target analytes.
