Congratulations, Dr. Hailin Wang, new SUMAN graduate!

Doctor Hailin Wang from the Superconducting Materials and Large Scale Nanostructures (SUMAN), and Advanced Characterization and Nanostructured Materials (ACNM) groups at ICMAB defended his PhD thesis entitled “Epitaxial growth of complex functional oxide thin films by green and sustainable chemical solution methods” on Tuesday, 15 December 2020. The PhD Thesis was supervised by Narcís Mestres (SUMAN group) and Benjamín Martínez (ACNM group). Congrats!

Abstract: Chemical solution deposition (CSD) techniques are promising methodologies to achieve epitaxial oxide thin films combining high performance with high easy scalability, environment friendly fabrication and low cost.

In this thesis, the polymer-assisted deposition (PAD), an aqueous environmentally friendly CSD method, is used to prepare derivatives of lanthanum manganite perovskite films, including La₂CoMnO₆, La₂NiMnO₆ double perovskites and La_0.92MnO₃ films, on SrTiO₃ or LaAlO₃ substrates. We evidenced that the particular growth process and crystallization conditions of PAD (very slow rate, close to thermodynamic equilibrium conditions) promote the high crystallinity and quality of the films, as well as favor high cationic ordering. The PAD technique allows obtaining complex oxide thin films of high microstructural quality suitable for spintronics applications.

The PhD Thesis was in the frame of the UAB Doctoral Programme in Materials Science, and the PhD Committe was formed by Amilcar Labarta, UB,  Barcelona, Spain (President), José Santiso, ICN2,  Bellaterra (Barcelona), Spain (Secretary), and  Adrián Carretero,  CNRS- Montpellier, France (Vocal).

Thank you Hailin and good luck in your future endeavours!
