In this work, a dielectrically modulated tri-material hetero stack gate (DM-TMHSG) MOSFET biosensor is designed for biosensing application to improve the sensitivity of the device. So, here the device is developed for the recognition of analytes such as Uricase, Ferro-cytochrome-C, Streptavidin, and Protein to assess the features of the biosensor. The various performance constraints like threshold voltage, threshold voltage sensitivity, current, current sensitivity, Subthreshold swing (SS), and SS sensitivity are investigated in the presence of only neutral biomolecules. All the constraints are simulated using the 2D TCAD platform. Simulation results showed that protein biomolecules offer better sensitivity as compared to other biomolecules in terms of current, threshold voltage, and subthreshold swing.
