: We report on the sensing mechanism of electrical detection
of deoxyribonucleic acid (DNA) hybridization for Au- and Cr-contacted
field effect transistors based on single-walled carbon nanotube (SWCNT)
networks. Barrier height extraction via low-temperature electrical
measurement provides direct evidence for the notion that the energy
level alignment between electrode and SWCNTs can be affected by DNA
immobilization and hybridization. The study of location-selective
capping using photoresist provides comprehensive evidence that the
sensing of DNA is dominated by the change in metal-SWCNT junctions
rather than the channel conductance.
