This paper includes sensitivity assessment of label-free biosensors using hetero dielectric Junctionless-TFET (HD-JL-TFET) thorough TCAD simulator. The fundamental structure, operation and design of a Junctionless-TFET (HD-JL-TFET) as biosensor are investigated in this paper. For the purpose of detecting the biomolecule, a nano-gap is added close to the source end between the gate and channel. To test the sensing potential, we adjusted the charge density and material dielectric constant (K) by comprehensive calibrated device simulation. For several biomolecules, the device's sensitivity was examined as surface potential, electron tunnelling rate, and conduction-valence band edge fluctuation. Additionally, the Id vs VGS features, the sensitivity to the drain current, and the ION/IOFF fluctuation are also examined. By contrasting neutral or charged biomolecules using various dielectric constants, the sensitivity characteristics of positive, negative, and neutral biomolecules are examined. The development of biosensors, which enable the rapid and precise detection of multiple biomolecules, has revolutionized the field of bioanalysis.

An accurate analytical model is presented for drain current of the heterojunction tunneling field effect transistor, taking into account the source depletion region, mobile charges and the effect of the drain voltage. This model accurately predicts the potential distribution not only on the surface but also within the semiconductor depth by utilizing newly formulated mathematical relationships. Using the tangent line approximation method and considering the channel region as well as the source depletion region' We analytically calculate the band-to-band tunneling current from the source to the channel by integrating the tunneling generation rate. Compared to simulation results, the proposed model demonstrates significant accuracy in predicting drain current.

The present study presents an innovative idea: an original design for a label-free biosensor utilizing H-shape channel configuration within a dielectrically modulated (DM) double-gate TFET (DGTFET) framework, which includes the incorporation of a drain pocket (DP). This design concept is introduced In this study, an analytical model for the DM DPDG-TFET has been created for the first time was formulated and subsequently verified through comparison with industry-standard simulation software (Silvaco TCAD). In this paper we have examine both the biosensor's sensitivity and its effectiveness when employed as a tunnel field-effect transistor (TFET) device. A comprehensive analysis of the device's performance has been conducted. The innovative configuration of the suggested TFET results in heightened sensitivity. Incorporating a drain pocket (DP) at the junction between the drain and channel effectively eliminates ambipolarity, showcasing a successful approach. The H-shape DM DPDGTFET design demonstrates its superiority over various devices documented in the literature. The presence or lack of electric charge in various biomolecules is examined in order to evaluate the device's sensitivity as a label-free biosensor.
