Silicon nanowireSilicon nanowires, also referred to as SiNWs, are a type of semiconductor nanowire most often formed from a silicon precursor by etching of a solid or through catalyzed growth from a vapor or liquid phase. Such nanowires have promising applications in lithium ion batteries, thermoelectrics and sensors. Initial synthesis of SiNWs is often accompanied by thermal oxidation steps to yield structures of accurately tailored size and morphology. SiNWs have unique properties that are not seen in bulk (three-dimensional) silicon materials.
AzoteL'azote est l'élément chimique de numéro atomique 7, de symbole N (du latin nitrogenium). C'est la tête de file du groupe des pnictogènes. Dans le langage courant, l'azote désigne le corps simple N (diazote), constituant majoritaire de l'atmosphère terrestre, représentant presque les 4/ de l'air (78,06 %, en volume). L'azote est le constituant la croûte terrestre par ordre d'importance.
