Noise immune dielectric modulated dual trench transparent gate engineered MOSFET as a label free biosensor: proposal and investigation.

We propose and investigate a biosensor based on a transparent dielectric-modulated dual-trench gate-engineered metal-oxide-semiconductor field-effect transistor (DM DT GE-MOSFET) for label-free detection of biomolecules with enhanced sensitivity and efficiency. Various sensing parameters such as the / ratio and the threshold voltage shift are evaluated as metrics to validate the proposed sensing device. Additionally, (the sensitivity) is also analyzed, considering both positively and negatively charged biomolecules.
