Abstract

In this paper, a Molybdenum Telluride (MoTe2) based dielectric modulated Junctionless Tunnel Field Effect Transistor (MoTe2-JLTFET) is proposed and investigated for detecting biomolecules like Biotin, APTES, Cellulose, DNA, and Gelatin. A nanocavity is introduced on the underlap of control gate and polar gate of device for sensing the biomolecules. The variation in the drain current, subthreshold slope (SS) and Ion/Ioff switching ratio are measured to assess the device's sensitivity for biomolecule recognition. MoTe2, a twodimensional Transition Metal Dichalcogenides (TMDCs) material has been employed in the channel instead of silicon due to its excellent physical and chemical properties. It is observed that the proposed device has less short channel effects, a lower SS and a greater switching ratio than a Silicon-based JLTFET (Si-JLTFET). The impact of biomolecule properties on device performance has been thoroughly analyzed in terms of dielectric constants, doping concentration, threshold voltage and different filling portions in the cavity
