Special Issue Information

Dear Colleagues,

New era concepts of Internet of things (IoT) and smart surfaces are now demanding transparent, flexible, and nanoscale devices and materials. In this regard, metal oxides have emerged as key materials, following from how metal oxide thin films, namely indium-gallium-zinc oxide (IGZO), were successfully applied for the backplanes technology. In fact, comparing with other technologies, such as polycrystalline/amorphous silicon, 2D transition metal dichalcogenides (TMDs) and graphene, metal oxides can be highly competitive since they present good reproducibility, large-area uniformity, and lower fabrication temperatures and costs, being compatible with flexible and transparent technology while still enabling good electrical and optical properties.

Moreover, metal oxide nanostructures have similarly been demonstrating excellent properties, and, while the implementation of nanostructures in devices and circuits still requires significant development, it would enable for very high levels of integrability and performance.

This Special Issue welcomes the submission of original papers and/or review articles focused on the fabrication of metal oxide semiconductors, in both the form of thin films or nanostructures, and their application in electronics.

Relevant topics may include (but are not limited to):

  • Metal oxide semiconductors characterization and fabrication;
  • Sustainable materials and processes;
  • Advances in the integration of metal oxide semiconductor nanostructures;
  • Transparent and flexible electronics;
  • Electronic devices such as field effect transistors, memristors, sensors, nanogenerators, and photodetectors;
  • Application of metal oxide semiconductors to electronic circuits or systems;
  • Devices’ modelling and simulation.

You may choose our Joint Special Issue in Electronic Materials.

This study introduces an innovative method for synthesizing Cadmium Oxide /Cadmium Sulfide/Zinc Oxide heterostructures (CdO/CdS/ZnO), emphasizing their potential application in solar energy. Utilizing a combination of electrochemical deposition and oxygen annealing, the research provides a thorough analysis of the heterostructures through scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), Raman spectroscopy, and photoluminescence (PL) spectroscopy. The findings reveal a complex surface morphology and a composite structure with significant contributions from hexagonal CdS and cubic CdO phases. The study highlights the uniformity in the distribution of luminescent centers and the crystalline quality of the heterostructures, which is evident from the PL analysis. The redshift observed in the emission peak and the additional peaks in the excitation spectrum indicate intricate optical properties influenced by various factors, including quantum confinement and lattice strain. The research demonstrates these heterostructures’ potential in enhancing solar cells’ efficiency and applicability in optoelectronic devices. This comprehensive characterization and analysis pave the way for future optimization and application in efficient and sustainable solar energy solutions. Full article
