UV-Assisted Gate Bias Cycling in Gas-Sensitive Field-Effect Transistors
Proceedings, 2018 Static and dynamic responses of a silicon carbide field-effect transistor gas sensor have been investigated at two different gate biases in several test gases. Especially the dynamic effects are gas dependent and can be used for gas identification.
