"Interstitial atoms in tungsten: Interaction with free surface and in situ determination of formation energy"
I. M. Neklyudov, E. V. Sadanov, G. D. Tolstolutskaja, V. A. Ksenofontov, T. I. Mazilova, and I. M. Mikhailovskij
The energy of formation of self-interstitial atoms has been experimentally determined using an energy analysis of low-temperature field evaporation of tungsten in a field-ion microscope. An experimental approach, based on the strong dependence of the threshold field for evaporation on the total energy of the surface atoms, is used. It was found that the excited atomic states can be produced by the release of the formation energy of self-interstitial atoms emerging at the surface. The experimental results are discussed in the framework of the image-hump model of field evaporation and compared with theoretical data on the energy of formation of interstitial atoms.

Received 17 July 2009; revised manuscript received 2 September 2009; published 7 October 2009.
A recently developed high-field technique of atomic chains preparation has made it possible to attain the ultrahigh resolution of field-emission electron microscopy (FEEM), which can be used to direct imaging the intra-atomic electronic structure. By applying cryogenic FEEM, we are able to resolve the spatial configuration of atomic orbitals, which correspond to quantized states of the end atom in free-standing carbon atomic chains. Knowledge of the intra-atomic structure will make it possible to visualize generic aspects of quantum mechanics and also lead to approaches for a wide range of nanotechnological applications.
