A Label-Free Dielectric-Modulated Biosensor Using SiGe-Heterojunction Dual cavity Dual Metal Electrically Doped TFET

Abstract The detection of biomolecules has been accomplished in this article by using the tunnel field effect transistor’s (TFET) bipolar nature. fabrication procedure made simpler, prices have gone down, and random dopant fluctuation (RDFs) eliminated charge plasma concept. objective work is to investigate performance a DopingLess- Dual Metal Gate- Cavity- HeteroJunction- Tunnel Field Effect Transistor (DL-DMG-DC-HJ-TFET) biosensor that can sense both ON ambipolar states. It feasible recognize many types concurrently taking into account cavities at tunneling junctions. suggested biosensor’s OFF state current reduced its sensitivity increased via use gate workfunction engineering bandgap engineering. investigated how presence proteins affects electrical properties such as energy band diagram (EBD), surface potential (SP), subthreshold Swing (SS), threshold voltage ( V T H stretchy="false">) , ratio $({I}_{ON}/{I}_{OFF}).$?> I O N / F . impact temperature, germanium mole fraction, position also analyzed work. A comparative analysis for drain presented considering different previous works.
