Dual-Cavity Triple-Metal Gate-Underlap Dielectric-Modulated Charge-Plasma-based TFET for the Biomolecules Recognition
In this era of technology, biosensors play an essential role in living life. Today’s research and investigation revolved around its higher responsiveness and speed of detection. Normal TFET has many disadvantages like fabrication complexity, random dopant fluctuation, and the lower ON-State current. We are introducing a device that is a Dual-Cavity Triple-Metal gate-underlap DM-CPTFET for label-free detection. This device has a dual cavity for sensing different types of biomolecules simultaneously. We used the tool i.e SILVACO ATLAS TCAD Simulator for the sensing applications. High K material and gate work function engineering help us to improve drain current and better sensitivity. We used this TCAD tool, for analyzing the different parameter variations like energy band variation, surface potential, transfer characteristic, and output characteristic using different biomolecules Gelatin(k=12), Keratin(K=8), Biotin(K=2.63), etc.
