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.
