Abstract :
We fabricated single electron transistor using DNA-assisted assembly of Au nanoparticles. Most devices exhibited clear Coulomb blockade oscillations. In contrast to conventional single electron transistors, however, the period of Coulomb oscillations was observed to depend on the temperature. Possible explanations are discussed.
