A Novel HM-HD-RFET Biosensor for Label-Free Biomolecule Detection.

The mortality of people worldwide caused by COVID-19 has enhanced the research interest to design and develop power-efficient, low-cost, and sensitive biosensors to detect a wide range of biomolecules or foreign particles that can cause severe negative impact on humans. A novel Bio-RFET biosensor with hetero-material (HM) for source/channel and drain regions and hetero-dielectric (HD) is proposed, which acts as an -MOSFET or a -MOSFET and -TFET or -TFET. This HM-HD-RFET biosensor senses the biomolecules by the label-free dielectric modulation (DM) technique.
