Epitaxial growth of BaZrO3 films on single crystal oxide substrates using sol-gel alkoxide precursors

“…The success of this process was established with the achievement of 1.0 V OCV at 650°C [31]. Numerous significant progresses across the globe are discussed in various articles [3,[32][33][34][35][36][37][38][39][40][41][42][43][44][45][46].…”

“…Hence, the newly generated alkoxide is less prone to hydrolysis, thereby allowing easy formation of gel instead of precipitate [35]. As for example, 2-methoxyethanol was used to dissolve Ba metal and partially substitute propoxide of zirconium propoxide for the fabrication of epitaxial BZY film.…”

Chemical solution deposition (CSD) technique is recently gaining momentum for the fabrication of electrolyte materials for solid oxide fuel cells (SOFCs) due to its costeffectiveness, high yield, and simplicity of the process requirements. The advanced vacuum deposition techniques such as sputtering, atomic layer deposition (ALD), pulsed laser deposition (PLD), metallo-organic chemical vapor deposition (MOCVD) are lacking in scalability and cost-effectiveness. CSD technique includes a variety of approaches such as sol-gel process, chelate process, and metallo-organic decomposition. The present chapter discusses briefly about the evolution of CSD method and its subsequent entry to the field of SOFCs, various solution methods associated with different chemical compositions, film deposition techniques, chemical reactions, heat treatment strategies, nucleation and growth kinetics, associated defects, etc. Examples are cited to bring out the history dating back to the discovery of amorphous zirconia film through the successful fabrication of the crystalline fluorite-type films such as yttria-stabilized zirconia (YSZ), scandia-doped ceria (SDC), and crystalline perovskitetype films such as yttria-doped barium zirconate (BZY) and yttria-doped barium cerate (BCY), to name a few.

“…Thus, further study on the buffer material is still required for the IBAD-MgO template. In this study, we have selected (BZO) as a potential buffer layer on the IBAD-MgO template since BZO shows an excellent chemical compatibility with YBCO and also small lattice-mismatch ( 0.5%) with MgO [15], [16]. We here report the effects of PLD processing parameters, including substrate temperature and ambient pressure , on the BZO buffer layers.…”

We report a successful fabrication of GdBa 2 Cu 3 O 7 (GdBCO) coated conductor on the ion-beam assisted deposition (IBAD) MgO template with a new buffer layer of BaZrO 3 (BZO). The BZO films were deposited on the IBAD-MgO template at various substrate temperatures ( S ) and oxygen partial pressures ( O 2 ) by pulsed laser deposition (PLD). In the broad ranges of S and O 2 , all BZO layers showed almost uniform in-plane texture (1 of 6 ), implying that BZO is an attractive buffer layer. The surface roughness of BZO layer was sensitive to O 2 but not to S . On the optimally processed BZO buffer layer with 5.1 nm RMS roughness, GdBCO coated conductor deposited at S of 750 C and O 2 of 400 mTorr exhibited 1 of 4.4 , c zero of 90.3 K, and c of 1.35 MA cm 2 (77 K, self-field). Index Terms-BZO buffer layer, GdBCO, IBAD-MgO, PLD.
