In this paper, using calibrated simulation we have reported a dielectric modulated epitaxial tunnel layer TFET (DM ETL-TFET) for the label-free detection of biomolecules.We have shown that due to vertical tunneling direction, the ETL-TFET exhibits $sim$3 orders of improvement in the ON-state current in comparison to its counterpart conventional TFET.In addition, Organic the proposed DM ETL-TFET biosensor shows $sim$4 orders, and $sim$1 order higher ON-state current sensitivity than the past reported core-shell junctionless NT-TFET, and DM NT-TFET biosensors, respectively.Moreover, in comparison to the lateral DM TFET, the proposed DM ETL-TFET shows $sim$310 mV higher threshold voltage sensitivity.Also, the subthreshold swing sensitivity of the CPU Cooling Fan proposed biosensor is found to be $sim$0.

63 for the keratin biomolecule.Although the proposed biosensor shows almost the same selectivity, the proposed DM ETL-TFET biosensor does not need a complex fabrication process flow, hence, reducing the fabrication cost.Our findings that the proposed biosensor is a lucrative alternative to the FET-based biosensors.
