Abstract
The present invention provides a single-electron device com posed of a necklace of about 5000 nanoparticles. The linear necklace is self-assembled by interfacial phenomena along a triple-phase line of fiber, a substrate and electrolyte containing nanoparticles. A variety of combinations of nanoparticles, Such as Au and CdS nanoparticles, may be used to form a necklace. The I-V measurements on the system show both coulomb blockade and Staircase, with high currents and high threshold voltage of 1-3 V. The present invention also provides methods for constructing Such a device.
