Abstract In recent years, label-free sensors have been studied extensively for biomolecule detections. Label-free biosensors based on MOSFETs could achieve high detection sensitivity, the subthreshold swing of such cannot break limitation 60 mV Dec −1 due to physical mechanism thermal electron emission. However, less than can be achieved in tunnel FETs working band tunneling (BTBT) mode. Usuall...

A comprehensive study of the drain current drift mechanism and hysteresis phenomena in fabricated p-channel junctionless ion-sensitive field-effect transistor (JL-ISFET) has been investigated for first time. The measurements have performed through transient analysis current, under different pH liquid-gate bias (Vlg). Further, time-dependent gate-capacitance (CG) also analyzed to see effect hydr...

A comparative evaluation of channel hot carrier (CHC) reliability and pursuance dopingless FET (DL JLFET) junctionless (JLFET) are studied for various dielectrics compared with conventional dielectric (SiO2) JLFET. The use such as vacuum near the drain high-κ (HfO2) source in DL JLFET (VacuHDL allows better against effects. simulation study has shown that VacuHDL terms Ion/Ioff ratio is improve...
