Solid-state dewetting of La0.6Sr0.4Co0.2Fe0.8O3±δ thin films during annealing

A review of wetting versus adsorption, complexions, and related phenomena: the rosetta stone of wetting

“…Examples include catalysis [101][102][103], porous electrodes [104,105], and more recently charge storage for memory applications [106][107][108].…”

Flame spray deposition of La0.6Sr0.4CoO3−δ thin films: Microstructural characterization, electrochemical performance and degradation

“…Particularly for the YSZ/LSM system, the reduced performance is assigned mainly to the surface-dominated oxygen transfer kinetics of the purely electronic conducting LSM cathode [5]. Therefore, alternative materials with mixed ionic-electronic conductivity (MIEC) have been investigated, such as La 1−x Sr x CoO 3−ı (LSC) [6,7], La 1−x Sr x Fe 1−x Co x O 3−ı (LSCF) [8,9], Ba 1−x Sr x Fe 1−x Co x O 3−ı (BSCF) [8,[10][11][12][13][14][15], and Ba 1−x Sr x Fe 1−x Zn x O 3−ı [14,16]. Due to the mixed conductivity, volume diffusion occurs in addition to surface diffusion and accelerates the oxygen transfer kinetics of these MIEC perovskites compared to LSM [5].…”

Low temperature synthesis by spray pyrolysis of La0.9Sr0.1Co0.2Fe0.8O3 thin films using ethanol and water as a solvent and their microstructural characterization

“…Beckel et al [1] observed a good performance of the LSCF film at lower temperatures with activation energy from 1.55 eV. Mukhopadhyay et al [19] showed that an increase strontium dopant on La site promotes a major conductivity in LSCF system, probably this occurs due to the oxygen vacancies formation.…”

“…According Beckel et al [1] during deposition LSCF films on substrate silicon at 255°C, a thin native oxide layer for the latter due to the processing at elevated temperatures is to be expected. In the substrates silicon and sapphire thermal treatment at 800ºC was observed reactions between La 0.5 Sr 0.5 CoO 3 thin with substrates forming secondary phases of Sr 5 Al 2 O 8 and La 2 O 3 [29].…”

“…Thin films are present in electronic materials [1], solar cells [2], sensors, coatings, superconductors [3,4], semiconductors [4,5], and fuel cells [6][7][8]. The use and application of thin films makes the work with low weight equipment possible, providing a higher return in the manufacturing process.…”
