About this Research Topic
Nanostructured metal oxides, particularly those with semiconducting properties, have gained considerable attention in the recent years as they can be potentially employed in electronic devices, including transistors, energy storage devices, and gas sensors. For these applications, much research efforts have been done to grow nanostructures, specifically in the form of thin film. Thin film, also termed as two-dimensional nanostructured material, has wide ranges of semiconducting properties as compared to the bulk solid one. It typically serves as a passivation/protective layer of a surface, a modified layer to improve the surface properties of solids, and/or an active layer. In order to make a device functional, a good quality of nanostructured oxide thin-film, with the thickness ranging from one nanometer to several micrometers, is required to be tailored and designed for electronic applications, including gas sensors.
Nanostructured oxide thin films are extraordinary, multifunctional, and possess outstanding properties with an enormous range of emerging applications. These include sensors, capacitors, photovoltaic solar cells, transistors, capacitors, light emitting diodes, spintronics, and energy storage devices. These oxides have several interesting properties, such as wide or large energy bandgap, high dielectric constant, good thermodynamic stability, and high conductivity. The development of exceptional properties and desired performance of these oxide thin-film materials are very much dependent on the morphology and the nanostructure of the materials, which can be tailored through fabrication and deposition techniques. They have been grown on various substrates by sputtering, sol-gel, hydrothermal, chemical vapour deposition (CVD), pulsed laser deposition (PLD), atomic layer deposition (ALD), molecular beam deposition (MBE), etc. Thus, the latest progress in the deposition techniques of these films and coatings are of interest as well. With the vast knowledge in this area, this Research Topic aims to publish original research and review papers, focusing on nanostructured oxide thin-film materials for electronic and sensing applications.
We invite researchers to submit papers which discuss on the development of nanostructured oxide thin-film materials, including multilayered thin films. The scope of the original research and review papers in this Research Topic includes, but not limited to, the following aspects:
• Synthesis, processing, and properties of nanostructured oxide thin-film materials, including modelling of the growth and reaction mechanisms of nanostructures.
• Advanced characterization techniques on nanostructured oxide thin-film materials.
• Advanced electronic and gas sensing device fabrication and development based on nanostructured oxide thin-film materials.
• Morphological, microstructural analysis, and micro-macro relationships of the observed properties and their modelling.
