a The XPS of Ge 3d and S 2p orbitals. b Raman spectrum of GeS film. c Atom configuration and bonding environment of pyramidal and tetrahedral Ge-centered structural motifs. d Comparison of the experimental RDF by electron diffraction method and simulated RDF obtained by DFT MD simulation. The inset is the corresponding electron diffraction pattern of amorphous GeS film.
