Performance analysis of dielectric modulated underlap FD-SOI MOSFET for biomolecules detection

A Novel Dielectric Modulated Misaligned Double-Gate Junctionless MOSFET as a Label-Free Biosensor

“…When considering protein biomolecules in the cavity region, the dielectric constant (K) is increased (K > 1), keeping charge (NBIO) at the Si-SiO2 layer at zero. Similarly, for examining the effect of DNA biomolecules, a non-zero charge is considered at the Si-SiO2 layer with the dielectric constant [3]. The misaligned double-gate structure is created by depositing a gate electrode on each side of the channel.…”

“…The need for a highly sensitive, reliable, and cost-effective biosensors has been a long-standing challenge in the field of medical diagnostics and biological research. In recent years, extensive research has been carried out to develop biosensors based on various technologies, such as surface plasmon resonance, quartz crystal microbalance, and field-effect transistors (FETs) [1][2][3]. Among these, FET-based biosensors have shown tremendous potential due to their high sensitivity, label-free detection, real-time monitoring capabilities, and potential for miniaturization [4][5][6][7][8].…”

“…This novel biosensor has the potential to revolutionize the field of medical diagnostics, drug discovery, and environmental monitoring. The proposed biosensor uses Cr 2 O 3 as a gate dielectric to improve the sensitivity of the device [3]. In this research paper, we propose a novel dielectric modulated misaligned double-gate junction less MOSFET (DM-MDG JL-MOSFET) structure as a label-free biosensor.…”

“…Cr 2 O 3 is an interesting material for FET-based biosensors because of its high dielectric constant, stability, and biocompatibility. The use of Cr 2 O 3 as a gate dielectric has been reported to enhance the capacitance of the gate and improve the sensitivity of FET-based biosensors [3,12]. However, to the best of our knowledge, the proposed DM-MDG JL-MOSFET biosensor structure has not been reported in the literature.…”

Tweaking the Performance of Dielectric Modulated Junctionless Double Gate Metal Oxide Field Effect Transistor-Based Label-Free Biosensor

“…Field-effect transistor (FET) biosensors have become attractive due to their potential for high sensitivity, low cost, scalability, miniaturization, and compatibility with complementary metal-oxidesemiconductor (CMOS) technology. 5,6 FET-based biosensors operate by detecting changes in the electrical properties of the FET in response to binding events between target biomolecules and a recognition element immobilized on the FET surface. 7 This technology has several advantages over traditional biosensing methods, including the potential for miniaturization, real-time monitoring, label-free detection, and integration with electronic readout systems.…”
