Ksenofontov V. A structure at the atomic level of nanosized and nanostructure metallic and carbon materials

Object: nuclear structure of nanosized and nanostructure materials and objects, and also processes of auto-emission, evaporation and deformation of nanoobjects in superstrong electric fields. The purpose: definition of the structure of nanosized and nanostructure metal and carbon materials at nuclear level, and also the determination of physical mechanisms of their nuclear structure and microtopography modification. Methods: high-resolution emissive field-ion microscopy and electron microscopy, low-field-ion microscopy, field time-flying mass-spectrometry, combined ionic and electronic microscopy, high-resolution scanning electronic microscopy and mathematical modeling of field ionic images of nanosized objects. Results: the new approach to consideration of experimental mass-spectrometer data of evaporation of conductive nanosized objects, based on the detailed analysis of the power spectrum of evaporation of polynuclear clusters and mathematical modeling of configurations of nanosized electrodes is developed at the solution of trajectory problems for non-uniform superstrong electric fields. For the first time the physical model of the field evaporation, which allowed describing the anisotropy of field evaporation and regional distribution of brightness of ionic-microscopic images of metals and alloys with various type of a crystal lattice, is developed. The defining role of cathode plasma formation processes and its expansion in processes of mechanical destruction of nanoobjects in superstrong electric fields is determined. Field of application: physics of solid state, nanophysics
