Influence of discrete energy spectrum on correlated single-electron tunneling via a mezoscopically small metal granule
نویسنده
چکیده
The current-voltage characteristic (IVC) of a system of two small series-connected tunnel junctions is calculated under conditions when the energy spectrum of the central electrode of the system is discrete. The form of the IVC depends substantially on the rate of energy relaxation on this electrode. I t is shown that at typical real values of the system parameters the global IVC singularities due to correlated single-electron tunneling should be preserved down to very small dimensions of the central electrode. At the same time, the system IVC should have a fine structure that reflects directly the structure of the energy spectrum of the central electrode.

Correlated Single-Electron Tunneling via Mesoscopic Metal Particles: Effects of the Energy Quantization
The existing theory of correlated single-electron tunneling in the double normalmetal tunnel junction is extended to the case of an ultrasmall central electrode of the structure. It is shown that the form of the I-V curve of such a system depends on the energy relaxation rate in this electrode. For realistic values of the relaxation rate, the large-scale shape of the dc I-V curve, which is asso...
متن کاملSpectroscopy of discrete energy levels in ultrasmall metallic grains
We review recent experimental and theoretical work on ultrasmall metallic grains, i.e. grains sufficiently small that the conduction electron energy spectrum becomes discrete. The discrete excitation spectrum of an individual grain can be measured by the technique of single-electron tunneling spectroscopy: the spectrum is extracted from the current-voltage characteristics of a single-electron t...

متن کاملSpin effects in ferromagnetic single-electron transistors
Electron tunneling in ferromagnetic single-electron transistors is considered theoretically in the sequential tunneling regime. A new formalism is developed, which operates in a two-dimensional space of states, instead of one-dimensional space used in the spinless case. It is shown that spin fluctuations can be significantly larger than the charge fluctuations. The influence of discrete energy ...
متن کاملTunneling via Individual Electronic States in Ferromagnetic Nanoparticles
We measure electron tunneling via discrete energy levels in ferromagnetic cobalt particles that are less than 4 nm in diameter, using nonmagnetic electrodes. Because of magnetic anisotropy, the energy of each tunneling resonance shifts as an applied magnetic field rotates the particle’s magnetic moment. We see both spin-increasing and decreasing tunneling transitions, but do not observe the spi...
