Ni-DNA based Y shape nanowire device development and characterization

POSTER

Abstract

Owing to the good charge transport and self-assembly property of Ni-DNA, it becomes one of the most promising one-dimensional conducting nanowire. Two-terminal Ni ions doping DNA (Ni-DNA) nanowire devices have been developed and characterized recently. It is of interest to understand the charge transport behavior in a Yshape Ni-DNA device. In this study Yshape Ni-DNA has been synthesized and the DNA is linked on a three-terminal nanodevice via selfassembled process. The $I-V$ curves of Yshape Ni-DNA indicated that this device exhibits negative differential resistance spectra between each two terminals. The further charge transport behavior and mechanism will be revealed in this study.\\ \\Keywords: DNA, Y-shape Ni-DNA, negative differential resistance
