| description | 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 <inline-formula><tex-math notation="LaTeX">$\sim$</tex-math></inline-formula>3 orders of improvement in the ON-state current in comparison to its counterpart conventional TFET. In addition, the proposed DM ETL-TFET biosensor shows <inline-formula><tex-math notation="LaTeX">$\sim$</tex-math></inline-formula>4 orders, and <inline-formula><tex-math notation="LaTeX">$\sim$</tex-math></inline-formula>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 <inline-formula><tex-math notation="LaTeX">$\sim$</tex-math></inline-formula>310 mV higher threshold voltage sensitivity. Also, the subthreshold swing sensitivity of the proposed biosensor is found to be <inline-formula><tex-math notation="LaTeX">$\sim$</tex-math></inline-formula>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. |
