Аннотация
The problem of the electric double layer at the interface of the metal (Al) -vacuum in the stationary approximation is considered. Detailed analysis of the structure of the electrical double layer at the metal - vacuum interface allowed us to establish that the magnitude of the electric field reaches the maximum value on the metal surface. The electron density at the metal boundary is a weakly varying electron temperature function. However, the temperature dependence becomes significantly noticeable on the spatial electron density profile outside the metal. The establishment of electroneutrality in a double electric layer is accompanied by the appearance of a spatial inhomogeneity of electrons in a thin near-surface layer of a metal. This inhomogeneity must be taken into account when formulating the boundary conditions in hydrodynamic models. The calculations also showed that the ion pressure on the metal surface is zero. But the spatial profile of the ion pressure under the influence of electric field forces becomes negative. In the case of external influence, the electric field forces may be too large, and may lead to the destruction of the surface area of the metal.
