· The CSFET sensors operate at room temperature and are chemically gated with a chemicalsensitive layer, which upon exposure to a target gas, induces a channel threshold voltage shift. Room temperature gas sensors may typically suffer from effects such as poisoning and slow recovery to baseline after gas exposure.
Highly sensitive and selective gas and volatile organic compound (VOC) sensor platforms with fast response and recovery kinetics are in high demand for environmental health monitoring, industry, and medical diagnostics. Among the various categories of gas sensors studied to date, field effect transistors (FETs) have proved to be an extremely efficient platform due to their …
