Sensitivity Analysis of Physically Doped, Charge Plasma and Electrically Doped TFET Biosensors

TFET based label-free biosensors are fast, sensitive and more power efficient as compared to CMOS biosensors, which prone short channel effects (SCEs). However, literature is flooded with various that have become the reason of dilemma for researchers during pandemic situations like COVID-19. Therefore, in this work, a physically doped (PD), charge plasma (CP) electrically (ED) dielectric modulated (DM) compared, cover almost entire range doping junctionless devices. Also, we found ED provide better current sensitivities 5.10 × 107, 4.77 108 7.11 biomolecules K=12, positive charge= 1 1013 C/cm2 negative -1 respectively. Hence, ED-DM-TFET can act promising candidates detection identification quality.
