Abstract
We investigate the electronic transport properties of a deoxyribonucleic acid (DNA)-conjugated carbon nanotube (CNT) field effect transistor (CNTFET) device. The CNTFET exhibited a strong decrease of the drain current after DNA conjugation. The observed decrease can be explained by the formation of new scattering centers induced from defects at CNT–DNA binding spots. These surface scattering centers will decrease the transmission probability in CNTs. These results can be applied to biosensors, which detect the amount of conjugated DNA molecules.
