• We have investigated the geometric structure of the so-called Ca/Si(111)-($5\times 1$) surface using low-energy electron diffraction (LEED) and high-resolution core-level photoelectron spectroscopy. In LEED, dim extra spots besides the $\times 5$ spots were observed after cooling the sample to 100 K. The positions of these dim spots reveal that this phase has a $\times 2$ periodicity along its one-dimensional (1D) chains. In Si $2p$ core-level spectra, we observed five surface components. By considering the energy shift and intensity of each surface component and the 0.3 ML Ca coverage, we propose a structural model of this surface.
