Abstract

The structural component DeltaV_st(roarr) of the Si(111)-vacuum-SiO₂(100) system is calculated using the Green´s functions of the nonlocal Poisson equation. DeltaV_st(roarr) is determined by the interaction interference of the microscopic structure of the two surface in the narrow vacuum gap. It is shown that the DeltaV_st(roarr) in the case of small anode-to-cathode distance L (~ 0.3-2 nm) determines the lateral changing of the potential barrier height in the vacuum gap which results to the origin of ordered long-period lattice of the emission centers inside a superthin vacuum gap
