A gassensor based on tunnelfieldeffecttransistor (TFET) is proposed that leverages the unique current injection mechanism in the form of quantummechanical bandtoband tunneling to achieve substantially improved performance compared to conventional metaloxidesemiconductor fieldeffecttransistors (MOSFETs) for detection of gas species under ambient conditions.

Chemical Gated Field Effect Transistor by Hybrid ...

+

Gas sensors based on metaloxidesemiconductor transistor with the polysilicon gate replaced by a gas sensitive thin film have been around for over 50 years. These are not suitable for the emerging mobile and wearable sensor platforms due to operating voltages and powers far exceeding the supply capability of batteries. Here we present a novel approach to decouple the chemically sensitive ...

Compared with those with pure PMMA dielectric, the sensitivity of OFET sensors with hybrid dielectric had two orders of magnitude enhancement from % to 30%. The GO/PMMA hybrid dielectric based OFET also shows good selectivity for NH3 against H2S, SO2, and NO2. By analyzing the hybrid dielectric and the 6,13bis(triisopropylsilylethynyl) pentacene (TIPSpentacene) film through utilizing ...

DE102005008051A1 Gas sensor with field effect transistor ...

+

A gas sensor includes an openpore gassensitive layer (8) whose electrical characteristics are read by a FET (11). The sensitive layer is applied directly to the insulation of the FET, passing around an air gap. The insulation is located directly above the channel region of the FET or cooperates indirectly with the FET via a floating gate electrode (20).
