Knowra Hydrogen telluride Hydrogen telluride Hydrogen telluride is the colorless, highly toxic, flammable compound H₂Te, composed of hydrogen and tellurium. It is the heaviest hydrogen chalcogenide commonly discussed as a discrete molecular hydride.
Hydrogen chalcogenide : A binary compound formed between hydrogen and a chalcogen element. H₂Te is the tellurium member of this chemical family.
Chemical vapor deposition : A process that forms solid films by chemical reactions of vapor-phase precursors. Hydrogen telluride can serve as a tellurium-bearing precursor in vapor-phase deposition.
Water : A polar molecular compound with the formula H₂O, liquid under ordinary conditions. Water is the lightest group-16 hydride and contrasts sharply with volatile, unstable H₂Te.
Chalcogen : An element in group 16 of the periodic table, including oxygen, sulfur, selenium, and tellurium. Tellurium's placement among the chalcogens predicts the broad family resemblance of H₂Te.
Hydrogen sulfide : A colorless, toxic, flammable gas with the formula H₂S. Replacing sulfur with tellurium preserves the hydride pattern but changes stability and physical behavior.
Tellurium thin films : Thin layers of elemental tellurium deposited on a supporting surface. Decomposition of a tellurium precursor such as H₂Te can supply tellurium for film growth.
Ammonia : A pungent, colorless molecular compound with the formula NH₃. Its strong hydrogen bonding and comparatively high boiling point contrast with H₂Te's weak intermolecular attractions.
Molecular geometry : The three-dimensional arrangement of atoms in a molecule. The bent geometry of H₂Te follows from electron pairs around its tellurium atom.
Hydrogen selenide : A toxic, flammable hydrogen compound with the formula H₂Se. It is the lighter neighboring hydride in the same group, useful for comparing trends down the chalcogens.
Semiconductor doping : The deliberate addition of impurities to a semiconductor to control its electrical properties. Hydrogen telluride has been considered as a tellurium source in semiconductor processing.
