Bismuth methoxymethylpropanolate (Bi(mmp)3) was used for the deposition of both bismuth oxide Bi2O3 and the growth of thin films of complex oxides such as SrBi2Ta2O9 (SBT). Bi(mmp)3 indicates similar decomposition behaviour to the Sr–Ta alkoxide precursor, demonstrating its suitability as a complementary source of Bi for SBT.[258]
Volatile donor functionalised Bi alkoxides, bismuth tris-dimethylaminoethoxide Bi(dmae)3 and bismuth tris-amyloxide Bi(OCH2(CH2)3Me)3, have comparable physical properties and decomposition characteristics with Sr[Ta(OEt)5(dmae)]2, a useful precursor for SBT deposition
