 Chemical field-effect transistor

A Chemical Field-Effect Transistor (ChemFET) is a type of field-effect transistor (FET) that is sensitive to the presence of specific chemicals or biochemical analytes. It operates based on the principle of modulating the conductivity of a channel between source and drain terminals by an electric field, where the gate of the transistor interacts with chemical species. **Key Features of ChemFETs:** 1.
