A praseodymium adduct, Pr(hfa)(3) . diglyme [(H-hfa = 1,1,1,5,5,5-hexafluoro-2,4-pentandione, diglyme = CH3O(CH2CH2O)(2)CH3)] has been synthesized. It has been applied as a Pr source for the metallorganic chemical vapor deposition (MOCVD) of praseodymium containing films on silicon substrate and compared with Pr(tmhd)(3) [(H-tmhd = 2,2,6,6-tetramethyl-3,5-heptandione)] precursor. Physical and thermal properties of both Pr(hfa)(3) . diglyme and Pr(tmhd)(3) precursors have been fully analyzed and their efficacy as MOCVD precursors for the growth of praseodymium oxide films have been fully tested.

Abstract
A praseodymium adduct, Pr(hfa)(3) . diglyme [(H-hfa = 1,1,1,5,5,5-hexafluoro-2,4-pentandione, diglyme = CH3O(CH2CH2O)(2)CH3)] has been synthesized. It has been applied as a Pr source for the metallorganic chemical vapor deposition (MOCVD) of praseodymium containing films on silicon substrate and compared with Pr(tmhd)(3) [(H-tmhd = 2,2,6,6-tetramethyl-3,5-heptandione)] precursor. Physical and thermal properties of both Pr(hfa)(3) . diglyme and Pr(tmhd)(3) precursors have been fully analyzed and their efficacy as MOCVD precursors for the growth of praseodymium oxide films have been fully tested. Depending on the oxygen partial pressure (p(O2)), different praseodymium oxide phases have been obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
