H2PbO2
H2PbO2 is an unstable, semiconducting lead-based compound primarily studied for its complex structural properties.
About H2PbO2
H2PbO2 is a hydrogen-lead-oxygen compound that exhibits semiconducting electronic behavior. Its structural complexity is evidenced by its presence across multiple independent materials databases, reflecting significant interest in its atomic configuration despite its challenging synthesis profile.
As a material that resides above the thermodynamic hull, H2PbO2 is considered inherently unstable under standard conditions. This metastable nature makes it a subject of theoretical study for researchers investigating the limits of lead-based chemical bonding and the formation of complex hydroxides.
Key Properties
Cross-validated computational properties for H2PbO2, 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.
