Fringe-fields-modulated double-gate tunnel-FET biosensor | Scientific Reports

In this section, we will analyze how different neutral and charged biomolecules affect the AC/DC performance of FFC-bio TFET. Additionally, we will assess the reliability of our proposed structure under non-ideal conditions, such as temperature variation and trap states. Figure 4 depicts the electric field contours of the device when the cavities are filled by Air, APTES (k = 3.57) and Gelatin (k = 12), respectively. It can be inferred that insertion of biomolecules with higher dielectric constants in the cavities increases the extension of the electric field lines in the source…
