Nonclassical behavior in the capacitance of a nanojunction.
نویسندگان
چکیده
The capacitance of a nanojunction formed by a scanning tunneling microscope (STM) tip and a two-dimensional gold cluster was measured through the single electron tunneling spectroscopy of a double-barrier tunnel junction. By decreasing the STM tip-cluster separation, it was observed that the capacitance first increases and then decreases at short separation. This characteristic clearly deviates from the classical behavior and provides evidence for potential quantum effects on the capacitance.

Electron tunneling through a monolayer of small metal clusters investigated by scanning tunneling spectroscopy
We have investigated the current-voltage characteristic of monolayers of seperated metal clusters of a size of 1.4 nm with a low-temperature ultrahigh vacuum scanning tunneling microscope. Apart from the usual charge-quantization phenomena, such as Coulomb blockade and staircase, negative differential resistance was observed by performing measurements at distinct locations on the cluster layers...
متن کاملNanocrystal shape and nanojunction effects on electron transport in nanocrystal-assembled bulks.
Bulk nanostructured materials are made from the assembly of octahedral PbSe nanocrystals. After thermal annealing, the artificial bulk demonstrates a large difference in behavior depending on the temperature, and a large variation of room-temperature resistivity of up to seven orders of magnitude. This variation originates from the high-indexed sharp edges of the octahedral nanocrystals. As the...
متن کاملGeneration of Nonclassical States of the Radiation Field in the System of a Single Trapped Atom in a Cavity within the First Order of the Lamb-Dicke Approximation
In this paper, we propose a theoretical scheme for the generation of non-classical states of the cavity field in a system of a single trapped atom via controlling the Lamb-Dicke parameter. By exploiting the super-operator method, we obtain an analytical expression for the density operator of the system by which we examine the dynamical behaviors of the atomic population inversion, the phase-spa...
متن کاملScanning tunneling spectroscopy of gold nanoparticles: Influences of volatile organic vapors and particle core dimensions
Scanning tunneling spectroscopy of hexanethiolate-protected gold nanoparticles was studied in the presence of volatile organic vapors. The particles were immobilized onto a Au(111) surface that was modified with a hexanethiol self-assembled monolayer. It was found that particle dimensions played a critical role in dictating the STS behaviors in response to exposure to organic vapors, with the o...
متن کاملCharacterization of Reservoir Heterogeneity by Capacitance-resistance Model in Water-flooding Projects
Tedious calculations and simulations are needed to obtain an efficient production scenario and/orproper field development strategy. Capacitance-resistance model (CRM) is proved to be a fastreservoir simulation tool using just the field-available data of production and injection rates. Thisapproach sets a time-constant and a weighting factor (or well-pair connectivity parameter...
