Special Issue Information

Dear Colleagues,

This Special Issue focuses on the latest advancements in epitaxial thin films grown using chemical methods. Epitaxial growth refers to the deposition of a crystalline thin film with a well-defined crystallographic orientation on a substrate. Chemical methods, such as metal–organic decomposition, chemical vapor deposition, sol–gel, and other related techniques, offer precise control over film growth, composition, and properties.

Topics covered in this Special Issue may include, but are not limited to, the following:

  1. Novel chemical methods used for epitaxial thin film growth;
  2. Advances in controlling film orientation and crystallographic properties;
  3. Growth mechanisms and kinetics of epitaxial thin films;
  4. Characterization techniques for evaluating epitaxial film quality;
  5. The impact of growth parameters on film properties and performance;
  6. Epitaxial thin films for electronic and optoelectronic applications;
  7. Epitaxial thin films for energy storage and conversion;
  8. Epitaxial thin films for catalysis and sensing applications;
  9. Emerging materials and systems for epitaxial thin film growth;
  10. Challenges and future directions in epitaxial thin film research;
  11. Surface decoration with nanostructures.

This Special Issue aims to provide a comprehensive overview of the state of the art in epitaxial thin film growth using chemical methods, highlighting the latest research findings, technological advancements, and potential applications. Researchers and scientists working in the field of thin film deposition, materials science, and related disciplines are encouraged to contribute their original research articles, reviews, and perspectives to this Special Issue.

This paper presents findings on the influence of hydrothermal deposition processing parameters (precursor concentration and deposition duration) on the characteristics of ZnO layers deposited on the surface of amorphous Fe-based fibres. The characteristics of the coated fibres, especially the deposited layer, were investigated from structural, morphological, chemical, thermal and magnetic points of view. It was found that the use of a zinc acetate-based solution of 0.05 M concentration and a deposition duration of 24 h leads to a continuous, thin and adherent layer of ZnO on the surface of the fibres. The thickness of the ZnO layer is 450–500 nm, as shown by TEM-EDX investigations. The ZnO coated fibres were used to prepare fibre-based soft magnetic composites via a cold sintering process. The composites obtained are the first reported soft magnetic composites based on amorphous fibres. The coercive field of the cold sintered composites is 3.5 to 8.6 times lower, and the maximum relative permeability is 2.4 times larger, than the best coercive field and the maximum relative permeability reported until now for a crystalline fibre-based soft magnetic composite. The initial relative permeability of cold sintered composites is constant up to the frequency of 1000 Hz. Full article
