Deep Insights of SiGe PNPN Tunnel FET Cavity Based Biosensors for Label Free Detection
Source abstract
Abstract
This paper reports a benchmark study on tunnel FET (TFET) biosensors by considering the effect of analyte conjugation in the nanogap cavity. A comparative investigation is carried out for the PNPN TFET biosensor with different source materials (i) Si (EG = 1.1 eV) (ii) Si0.5Ge0.5 (EG = 0.78 eV). A wide range of electrical characteristics are analyzed to predict the high sensitivity for both material cases. Further, the uniform variation of the biomolecule length (Lbio) along the nanogap cavity with neutral and charged analytes is investigated. Again, the impact of non-uniform filled profiles of the biomolecules such as step profile, concave, and convex in the cavity are systematically reported. Finally, the sensitivity as a parameter to measure the shifting of electrical characteristics for the biosensors is reported in a comparative manner.
