“…The operation principle of the FETs biosensors is depending on the charge carriers of the substrate materials [103], [104]. Therefore, there are usually two different kinds of FETs, the n-type FET biosensor with electrons as the main charge carriers and p-type with holes as the charge carriers [105]. In more details, for n-types FETs systems, the sensing elements that have been immobilized on the sensing channels will show more conductance if the probes detect positively charged molecules due to the accumulation of the charge carriers on the sensing channels.…”

Chemicals and pesticides contamination in the food, drinking water, and environment ecosystem have become one of the most serious problems for human public health in the world due to their large amount used and wide application in the agriculture industry. Therefore, the detection and analysis of contamination in the food and drinking water by using techniques that are simple and suitable for fast screening are important. This review gives an overview of the last trends and recent advances biosensors for chemicals and pesticides detection based on electrochemical, optical and mechanical transducers strategies. Furthermore, the biosensors are classified according to their immobilized biorecognition elements including aptamer, antibodies, enzymes, and molecularly imprinted polymers. The implementation of nanomaterials such as graphene, carbon nanotubes, and metals nanoparticles are also emphasized and discussed in this review, these nanomaterials provides remarkable features to the biosensors such highly sensitive and accurate which allowing efficient pesticides detection. In addition to highlighting and summarizing various novel sensors, this review also provided some drawbacks, challenging, prospects as well as the current efforts to enhanced optical sensors.

 Abstract: Continuous device scaling of tunnel field effect transistors (TFET) faces real challenges in low power VLSI applications. Here in this article, the major limitation of TFET i.e. Ambipolar conduction behavior has been thoroughly discussed and remedies to suppress the leakage current (I OFF ) has also been investigated. A thin pocket layers is incorporated in source and drain regions separately at Silicon on Insulator (SOI) TFET, keeping supply voltage (V DD ) at 0.5 V. The detail analytical modeling of surface potential distribution along the channel, electric field and tunneling current is derived in this paper. Using two-dimensional numerical device simulator, the various designs are modeled and validated with our proposed methodology. Non-local Band-to-Band tunneling (BTBT) is used for simulation purpose. It is observed that a drain pocket actually helps to reduce the ambipolar conduction and provide better drive current (I ON ) for fast switching. This further improves the I ON /I OFF ratio and also results better subthreshold swing (SS) as 27.43mV/decade to optimize the device characteristics.
