Abstract:
Research into novel two-dimensional (2D) materials has boomed over the past decade, with a bewildering diversity of distinct properties being discovered. In this work, layered PtSe2, grown by chemical vapor deposition and thermally converted to non-layered tetragonal PtSe, is experimentally and theoretically investigated. Notably, the resultant PtSe is distinctly metallic, which highlights the significance of sub-stoichiometric phases within transition metal dichalcogenide films. This shows that thermal conversion can drastically affect the atomic and electronic properties of these phases.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
