Room-temperature Coulomb-blockade-dominated transport in gold nanocluster structures
نویسنده
چکیده
In this paper we discuss the near-room-temperature electrical transport characteristics of structures made from ligand-stabilized metal clusters. The structures show threshold behaviour, nonlinear current–voltage characteristics and radio-frequency-induced plateaux consistent with Coulomb-blockade-dominated transport in disordered arrays of metal dots. Samples having triphenylphosphine and octadecanethiol ligand shells are found to have a 3 orders of magnitude difference in current above threshold. We discuss a possible explanation for this observation.

Fabrication and near-room temperature transport of patterned gold cluster structures
Ligand stabilized metal clusters are becoming of considerable interest for possible nanoscale electronics applications. In this article, we report the fabrication and near-room temperature electrical transport properties of structures made from the gold-cluster material Au55@P~C6H5!3#12Cl6. While other strategies to produce cluster arrays have been reported, this work is the first to use electr...
متن کاملThe Analysis of Coulomb Blockade in Fullerene Single Electron Transistor at Room Temperature
The Graphene based single electron transistor (SET) as a coulomb blockade device need to be explored .It is a unique device for high-speed operation in a nano scale regime. A single electron transfers via the coulomb barriers, but its movement may be prevented by coulomb blockade, so its effect is investigated in this research. The conditions of coulomb blockade and its controlling factors such...
متن کاملRoom-temperature single-electron charging detected by electrostatic force microscopy.
We use atomic force microscopy to measure electron addition spectra of individual Au nanoparticles that exhibit Coulomb blockade at room temperature. The cantilever tip charges individual nanoparticles supported on an ultra-thin NaCl film via single-electron tunneling from the metal back electrode. The tunneling is detected by measuring frequency shift and damping of the oscillating cantilever....
متن کاملOne-dimensional transport in bundles of single-walled carbon nanotubes
We report measurements of the temperature and gate voltage dependence for individual bundles (ropes) of single-walled nanotubes. When the conductance is less than about e/h at room temperature, it is found to decrease as an approximate power law of temperature down to the region where Coulomb blockade sets in. The power-law exponents are consistent with those expected for electron tunneling int...

In this article, the design and modeling details of room-temperature analog-to-digital converter (ADC) based on silicon quantum-dot (QD) single-electron transistors (SETs) is presented. In contrast to the conventional metal quantum dots, the use of silicon QDs in the scales of few nano-meters enhances the device operation and makes stable the Coulomb blockade and Coulomb oscillation regimes at ...
