Brief description of the Research Team / Research Group / Department
The Physics of Electronic Materials Group (FINE Group) is a consolidated research team composed by 8 researchers as staff members, 4 postdoctoral researchers and 5 PhD students, which has been working steadily on the study of optical and electronic properties of semiconductors nanostructures for more than 25 years.
We have been involved in several international projects, such as a Marie Curie Training Site and TPVCell European Training Network (ETN); Bilateral actions with Germany, Portugal, Italy and France, one H2020 European project, devoted to batteries, and two consecutive USA AFOSR projects on gallium oxide nanostructures.
The FINE Group manages its own facilities at the UCM premises to carry out experimental research on an independent basis. The main equipment consists of five scanning electron microscopes (SEM) with advanced techniques as cathodoluminescence (CL), electron backscatter diffraction (EBSD) or energy dispersive X-ray microanalysis spectroscopy (EDS) to study structural and optical properties. A high-resolution spectrofluorimeter with a closed-cycle He cryostat, an optical confocal-Raman microscope and an AFM complete the battery of equipment for materials characterization. Its infrastructure enables a thorough materials science research, quite complete and not usually available in a single research group.

Research lines / projects proposed
The scope of the research activity is the study of semiconductor nanostructures, especially those based on the ultra-wide bandgap gallium oxide, with the aim to investigate their structure, morphology and physical properties, mainly oriented to photonics applications. We have developed synthesis routes that enable us to get reproducible nanomaterials with different morphologies (nanowires, nanorods, nanobelts, nanomembranes, hierarchical structures, complex nano-heterostructures,...). In addition, a full characterization of the obtained nanomaterials is carried out in the group premises. We study the local properties of the obtained nanostructures with high spatial resolution with the aid of, but not only, electron microscopy and optical spectroscopy related techniques.
We tune the physical properties in several ways: doping (optically active impurities, carrier concentration); morphology (branched structures, photonic artificial structures, optical cavities…); and dimensionality (hybrid structures with nanowires/ultrathin films) of the oxide based nanostructures. One of the active lines is the design, optimization and application of optical cavities based on the previously synthsized nanostructures.
Some current projects to illustrate our research lines are:
- "Light-matter interaction in nano-membranes of wide bandgap metal oxides for self-powered devices" (2022-2025). National project.
- "Development of a multifunctional optical sensor based on gallium oxide microcavities” (2024-2025). National proof of Concept project.
- "Gallium oxide nanostructures for energy saving and telecommunications" National project for ecological and digital transformation (2022-2025).
- "p-n heterojunctions of emergent wide band gap oxides for self-powered UVC sensing". European M.ERA.net project. (2023- 2026) Coordinated by UCM, Partners: Nanovation (France) and Technical University Dresden (Germany).
- “Exploring optical cavities based on gallium oxide nanomaterials”. Air Force Office of Scientific Research (2023-2026). USA.
-"Advanced Materials Complementary Plan", MAD2D-CM-UCM-4: "Bidimensional disruptive material " (CM y PRTE) (2022-2025). National project.
