Figure 1

Structure of the semiconducting 2H and the metallic 1T phase of MoS\(_{2}\) and the directional excitation of an electron into unoccupied S3p states following absorption of linearly polarized X-rays at the S L\(_{1}\)-edge in the CHC experiment. (a) Lithium deposition onto 2H-MoS\(_{2}\) leads to concomitant intercalation/adsorption of Li\(^{+}\) cations and electron injection, causing the phase transition and formation of 1T-Li\(_{\mathrm{x}}\)MoS\(_{2}\). (b, c) Crystallographic structures in top- and side-views of a monolayer of the 2H and the 1T phase. CHC spectroscopy prepares selectively in-plane (\(\parallel\)) and out-of-plane (\(\perp\)) S3p excited states. Black, yellow and blue spheres represent Mo, S and Li atoms, respectively. The crystallographic structure was build using Avogadro software version 1.2.032 and edited with Inkscape software version 0.92.3 (www.inkscape.org).
