Lithium cyclopentadienide has been tested as ALD precursor. Lithium containing films were obtained by ALD from LiCp and water. This product was also applied as the dopant precursor for the growth of lithium-doped ZnS epitaxial layers on GaAs substrates by MOVPE. LiCp was used as a dopant for the growth of Li-doped ZnSe films by atmospheric MOCVD at 500°C, with ZnMe2 and SeMe2 used as Zn, Se source materials. See link below

Ereztech manufactures and sells this product in small and bulk volumes. Glass ampules, bottles or metal ampules or bubblers are available for packaging. For additional analytical information or details about purchasing LI3974 contact us at
