δ-Bi2O3 thin films deposited on dense YSZ substrates by CVD method under atmospheric pressure for intermediate temperature SOFC applications

Thin films for micro solid oxide fuel cells

“…In the field of Bi 2 O 3 -based electrolytes, ␦-Bi 2 O 3 thin films have recently been produced by CVD [189][190][191]. The authors reported that ␦-Bi 2 O 3 thin films remain stable even down to temperatures of 350 • C. The highly conductive ␦-Bi 2 O 3 changes usually to phases with lower symmetry and low conductivity between 730 • C and 650 • C for microcrystalline Bi 2 O 3 -based ceramics (Fig.…”

Structural, morphological, and optical properties of Bi2O3 thin films grown by reactive sputtering

“…The most used methods in the synthesis of Bi 2 O 3 thin films are chemical vapor deposition [24,25], sputtering [26][27][28][29][30], electrodeposition [31,32], electrophoretic deposition [33] and sol gel methods [34]. There are rather few studies [24,26,27,35] about the influence of the influence of deposition parameters onto the structure and morphology of Bi 2 O 3 deposited films.…”

Synthesis and Materials Chemistry of Bismuth Tris-(di-i-propylcarbamate): Deposition of Photoactive Bi2O3 Thin Films

“…(ferroelectric perovskites) 9, 10 and Bi 2 Sr 2 CaCu 2 O 8 (high temperature superconductor). 11 Existing CVD precursors for bismuth oxides include BI 3 , [12][13][14][15][16][17][18] Bi(NO 3 ) 3, 19 BiPh 3 20- 22 and related bismuth aryls 23 and alkyls, 24 β-diketonates such as Bi(thd) 3 (thd = tetramethylheptane-dione), 23,25,26 and both simple and functionalised alkoxides, [27][28][29] all summarised in refs. 5 and 28.…”

“…Bismuth carbamates are, therefore, possible precursors for Bi 2 O 3 , a material exploited either alone or, more significantly, as a component of more complex materials such as Bi 2 Sn 2 O 7 (catalyst, CO sensor), , BiFeO 3 (a multiferroic compound), Bi 4 YTi 3 O 12 and SrBi 2 Ta 3 O 9 (ferroelectric perovskites), , and Bi 2 Sr 2 CaCu 2 O 8 (high temperature superconductor) . Existing CVD precursors for bismuth oxides include BI 3 , − Bi­(NO 3 ) 3 , BiPh 3 − and related bismuth aryls and alkyls, β-diketonates such as Bi­(thd) 3 (thd = tetramethylheptane-dione), ,, and both simple and functionalized alkoxides, − all summarized in refs and . However, of these only the three alkoxides − are single-source precursors (SSPs), the remainder requiring a co-reactant, usually O 2 .…”
