Rapid Detection of Biomolecules in a Junction Less Tunnel Field-Effect Transistor (JL-TFET) Biosensor

In this paper, we present a double gate JL-TFET based biosensor by varying the dielectric constant to detect various biomolecules through label-free detection technique. An investigation regarding properties and behavior device has been investigated with help of Silvaco TCAD. It is observed that Junction less TFET advantageous over JLFET TFETdue absence junctions. The proposed shows reduced short channel effects, lower subthreshold swing along higher voltage gain. biomolecule done inside cavity different electrical parameters such as electric field, sensing current, threshold transconductance are observed. change in voltage, drain used metric sensitivity presented for detection. Biomolecule position have find out their effect on parameter.
