Atom Probe Field Ion Microscopy |

Abbreviated Series Title |
Atom-probe field-ion microscopy (APFIM) was employed to study the phase separation process in a Cu-33.3at%Ni-1.7at%Cr ternary alloy. Formation of the coherent second phase was clearly observed after aging for 15 min at 823 K. Although no discrete precipitates were recognized in the Ne-ion image before 15 min aging, APFIM results showed a broadening in the concentration fluctuations. A grand-canonical (Gaussian) distribution was used to described the time evolution of the frequency distribution of Ni in the composition profiles. From the logarithmic plot of the relative change in variance versus aging time, the relaxation time for the clustering of Ni was determined. |

Field Emission |
|
The effect of the temperature gradients and the electric field existing in the bulk of a metallic cathode on its field emission characteristics has been analyzed. It has been established that, at high emission current densities, the nonequilibrium additive to the electron distribution function increases the fraction of electron emitted with energies close to the Fermi level, as compared to the equilibrium case. Therefore, the form of the energy distribution of the emitted electrons changes and the energy flux through the emission boundary increases. |

Field Emission |
|
The effect of penetration of an external electric field into a cathode being in the nonequilibrium superconducting state and the cathode emissive properties have been calculated. The state of nonequilibrium superconductivity in its turn, is caused by the emission process itself. |

The adsorption of an atom with one valence electron on a metal surface and the field desorption of this atom are considered in this paper. A very simple one-electron model is shown to describe properly the general features of the processes considered. |
