Abstract: The results of a study of the crystal structure and surface conductivity of a Si(111) silicon substrate with a reconstructed surface after deposition of submonolayer doses of lithium are presented. We used the method of low energy electron diffraction to study changes in the structure of the crystal lattice of the surface, as well as the four-point probe method for measuring the conductivity of substrates under in situ conditions. As the initial surfaces, we used the Si(111)7 $\times$ 7 reconstruction of an atomically clean silicon substrate, and the reconstructions obtained by adsorption of 1 ML of gold, lead, and bismuth atoms: Si(111)$\beta$ – $\sqrt{3}$ $\times$ $\sqrt{3}$ – Au, Si(111)1 $\times$ 1 – Pb and Si(111)$\beta$ – $\sqrt{3}$ $\times$ $\sqrt{3}$ – Bi, respectively.

Keywords: silicon surface, adsorption, surface reconstruction, surface conductivity, low-energy electron diffraction.
