Nanotip Fashioning and Nanosource Characteristics over the topmost atom of the protrusions allows these nanotips to be single-atom sources of electrons and metallic ions. The corresponding emitted beams present properties specific to the atomic dimension of the sources. The electron energy distribution and local heating during field emission from such tips are reported and discussed.

Electron Emission from Nanometer-Size Metallic Clusters: Electronic States and Structural Stability emission states that are revisited as time progresses. This phenomenon is attributed to a rearrangement of the cluster structure and/or orientation on the substrate and provides new evidence of multiple ‘isomeric’ structures for small clusters of metallic atoms.

Miniaturized Electron Microscopenot to be demagnified. In addition, the reduced aberrations of a micro-lens system allow high brightness to be achieved. Thus, even at low voltages, small beam diameters with high beam currents can be obtained.

On the Energy Dissipation in Field Emission and Tunneling Microscopyse tunneling distances there is more power to be dissipated in the emitting than in the receiving electrode which is not expected theoretically. Our results are compared with a theoretical estimate based on the free electron model for the electrode materials and tunneling across a planar vacuum gap.
