Strong Electron Tunneling through Mesoscopic Metallic Grains
We describe electron transport through small metallic grains with Coulomb blockade effects beyond the perturbative regime. For this purpose we study the real-time evolution of the reduced density matrix of the system. In the first part of the paper we present a diagrammatic expansion for not too high junction conductance, h/4πeRt ∼ 1, in a basis of charge states. Quantum fluctuations renormaliz...
متن کاملStrong coupling between single-electron tunneling and nanomechanical motion.
Nanoscale resonators that oscillate at high frequencies are useful in many measurement applications. We studied a high-quality mechanical resonator made from a suspended carbon nanotube driven into motion by applying a periodic radio frequency potential using a nearby antenna. Single-electron charge fluctuations created periodic modulations of the mechanical resonance frequency. A quality facto...
متن کاملRoom Temperature Hydrogen Sensor Based on Single-Electron Tunneling Between Palladium Nanoparticles
In this paper, we present the results of single-electron tunneling in two-dimensional (2D) hexagonal closed packed arrays of palladium nanoparticles. After inspecting the emergence of Coulomb blockade phenomena, we demonstrate the possibilities of using these arrays as a single-electron tunneling based hydrogen sensor. We assumed arrays of palladium nanoparticles with diameters of 3.5 and 6...
متن کاملStrong Electron Tunneling through a Small Metallic Grain
Electron tunneling through mesoscopic metallic grains can be treated perturbatively only provided the tunnel junction conductances are sufficiently small. If it is not the case, fluctuations of the grain charge become strong. As a result (i) contributions of all – including high energy – charge states become important and (ii) excited charge states become broadened and essentially overlap. At t...
متن کاملElectron tunneling through alkanedithiol self-assembled monolayers in large-area molecular junctions.
The electrical transport through self-assembled monolayers of alkanedithiols was studied in large-area molecular junctions and described by the Simmons model [Simmons JG (1963) J Appl Phys 34:1793-1803 and 2581-2590] for tunneling through a practical barrier, i.e., a rectangular barrier with the image potential included. The strength of the image potential depends on the value of the dielectric...
