Comparative Performance Analysis of the Dielectrically Modulated Full- Gate and Short-Gate Tunnel FET-Based Biosensors (2015, background): “THE label-free detection of biological species is the key advantage of using field-effect-transistor (FET)-based biosensors, where the intrinsic properties, such as dielectric constant and charge density of the target biomolecules, are exploited for the detection [1]–[13].”
A Charge-Plasma-Based Dielectric-Modulated Junctionless TFET for Biosensor Label-Free Detection (2017, background): “Apart from this, the scaling of FET (bulk MOSFET) for compactness and performance improvement of biosensor equipments gives rise to the following limitations: detection time is very large due to kT /q limit [subthreshold swing (SS) > 60 mV/decade], short channel effects, drain-induced barrier loweri”
