(a) Surface potential plot of CP-TMD-HJ-TFET biosensor along the channel-length at V_gs = 1.5 V, V_ds = 0.5 V for various dielectric constants (k) of biomolecules, (ρ = 0). (b) Surface potential plot of CP-TMD-HJ-TFET biosensor along the channel-length at V_gs = 1.5 V, V_ds = 0.5 V for different charge densities (C/cm²).
