In this letter, we present a study that highlights the importance of electrostatic effects on DNA sequence orientation, and the subsequent influence on the functioning principles of nanogap embedded dielectric-modulated field effect transistor (DMFET) biosensors. We find that the orientation of DNA molecules is responsible for governing the sensitivity and dominance of charge or dielectric constant effect in nanogap embedded FET devices. Using 2-D TCAD simulations, the study not only provides a… CONTINUE READING
