Investigation into MoTe2 Based Dielectric Modulated AMFET Biosensor for Label-Free Detection of DNA Including Electric Variational Effects

Due to the limitations of Silicon, Transition metal dichalcogenides (TMD) based biosensors are popular in recent times. In TMD family, Molybdenum telluride (MoTe2) is being studied a lot for different biosensing applications. However, DNA detection using TMD-based DMFET, effect electrical variations has not been before. Also, impact DNA-Electrode interaction on transducer level DMFET yet be studied. this article, we have proposed Accumulation Mode Field Effect Transistor (AMFET) possible dielectric modulated application. The study focused including electric due surface interaction. We done circuit-level analysis structure having deeper insights into its performance under various orientations nanogap. also presented benchmarking highlight superior sensitivity (ΔVth = 700 mV at K 8). back-gate bias included. obtained significant variation threshold voltage shift suggesting strong MoTe2 AMFET.
