dc.description.abstract | Carbide-derived layered Ti3SiC2 has an unusual combination of electrical, thermal and mechanical properties. The structure of Ti3SiC2 has been refined from Rietveld analysis of neutron diffraction patterns. The c-axis stacking sequence includes double layers of distorted edge-sharing CTi6 octahedra, reminiscent of the TiC structure. The double layers are separated by square-planar Si sheets. Bond lengths and angles were measured to greater accuracy than in previous studies. The refined structure is used in conjunction with data from X-ray photoelectron spectroscopy (XPS) to hypothesize that the origin of the observed high electrical conductivity is with the Ti–C blocks. The XPS analysis shows that both Ti and C species are exceptionally well screened, even in comparison with other carbides. Also, surface-specific compositional analysis by XPS shows that freshly prepared fracture faces exhibit relatively high Ti abundance while the Si abundance is low, in comparison with expected bulk stoichiometry. | |
