Comprehensive review on charge plasma based junction less TFET biosensor

Abstract

Now a days there is a dramatic increase in interest in next-generation biosensors for use in point-of-care (PoCT) devices. A potentiometric device is designed using semiconducting materials. It is gaining attention as a potential tool for creating advanced biosensors. The Classical Field Effect Transistor (CFET) based biosensors have some limitations because of short channel effects (SCEs). Thus, TFET based biosensor devices are required to resolve these issues. Comprehensive and systematic study of the junction-less and doping-less TFET-based biosensor is conducted to achieve label-free detection of biomolecules. Compared to junction-based TFET biosensors, the sensitivity of the junction-less TFET biosensors is better. Because the problem of excessive leakage current is eliminated. This review specially focused on the latest JLTFET device is studied to make the better understanding of the technology incubation to the upcoming researchers. Performance parameters like, ON current (I_ON), device sensitivity, switching current ratio (I_ON/I_OFF), and the subthreshold swing are compared.
