摘要

A range of "single source" Sr-Nb and Sr-Ta heterometal alkoxides precursors are investigated as potential sources for liquid injection MOCVD (metalorganic chemical vapour deposition) and ALD (atomic layer deposition) of SrBi_2Ta_2O_9 (SBT) and SrBi_2(T_xNb_(1-z))_2O_9 (SBTN). These "single source" precursors are designed to alleviate the mis-match between conventional Sr and Ta or Sr and Mb sources. Strontium-tantalate and strontium-niobate thin films were deposited on silicon using the "single source" alkoxide precursors [Sr{Ta(OEt)_5(dmae}_2] and [Sr{Nb(OEt)_5(dmae)}_2] (dmae = OCH_2CH_2NMe_2), and the optimum temperatures for deposition of stoichiometric SrTa_2O_6 and SrNb_2O_6 were determined. Separate ALD studies of [Sr{Ta(OEt)_5(dmae)}_2] and [Sr{Ta(OEt)_5(mee)}_2] (mee = OCH_2CH_2OMe) for the growth of Strontium-tantalate were carried out to assess precursor suitability for this technique. Liquid injection MOCVD of Bi-oxide films using Bi(mmp)3 indicates similar decomposition behaviour to the Sr-Ta and Sr-Nb alkoxides, demonstrating its suitability as a complementary source of Bi for SBT, SBN and SBTN.
