InO
InO is an indium-based oxide semiconductor that is typically found to be thermodynamically unstable compared to other oxides in the same chemical family.
About InO
InO is a semiconducting oxide that belongs to the broader class of wide-bandgap oxide semiconductors. While it shares elemental components with more common indium oxides, it represents a distinct stoichiometry that has been the subject of extensive structural investigation across materials databases.
Due to its position above the thermodynamic hull, this compound is generally considered unstable under standard conditions. Its study is primarily driven by the need to map the complex phase space of indium-oxygen systems and understand the fundamental electronic behavior of sub-oxides in this semiconductor family.
Key Properties
Cross-validated computational properties for InO, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
Within the wide-bandgap oxide semiconductors class.
In contrast to highly stable and widely utilized wide-bandgap semiconductors like ZnO or the more common In2O3, InO is characterized by its relative thermodynamic instability. While its siblings often serve as robust transparent conductive oxides or dielectric layers, InO remains a more elusive, theoretically intriguing member of the indium-oxygen system.
