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.
