Transition-Metal Doping for Tailoring the Electronic, Magnetic, Optical, and Energy-Related Properties of Functional Materials

Transition-metal doping has emerged as a powerful strategy for controlling the structural, electronic, magnetic, optical, catalytic, and transport properties of functional materials. By introducing transition-metal ions into host lattices, researchers can modify local coordination environments, electronic band structures, charge-carrier concentrations, defect populations, magnetic interactions, and interfacial phenomena. These changes can generate functionalities that are absent in pristine materials and provide new opportunities for designing materials for advanced electronic, spintronic, optoelectronic, sensing, catalytic, and energy-storage technologies. This Research Topic aims to present recent theoretical and experimental advances in transition metal-doped functional materials, with particular emphasis on understanding the relationships among dopant chemistry, crystal structure, defect states, electronic configuration, and macroscopic physical properties. The collection will cover bulk materials, nanoparticles, nanostructures, thin films, heterostructures, and two-dimensional materials, including transition-metal dichalcogenides, oxides, chalcogenides, perovskites, carbon-based materials, and other emerging condensed-matter systems. Particular attention will be given to the mechanisms through which transition-metal doping influences band-gap engineering, charge transport, carrier mobility, magnetic ordering, spin polarization, optical absorption and emission, lattice distortion, phase stability, surface reactivity, and electrochemical behavior. Studies combining advanced characterization techniques with firstprinciples calculations, atomistic simulations, or multiscale modeling are especially encouraged, as they can provide deeper insight into dopant incorporation, site preference, oxidation states, defect compensation, and structure–property relationships. The Research Topic welcomes original research articles, reviews, perspectives, and methodological studies addressing, but not limited to: • Transition-metal doping of semiconductors, oxides, chalcogenides, perovskites, and twodimensional materials; • Dopant-induced electronic, magnetic, optical, and structural modifications; • Defect engineering, oxygen vacancies, charge compensation, and local lattice distortion; • Doping-controlled charge-transfer and carrier-transport mechanisms; • Transition-metal-doped materials for batteries, supercapacitors, catalysis, sensing, spintronics, and optoelectronics; • Experimental identification of dopant location, oxidation state, and chemical environment; • First-principles calculations and theoretical modeling of doped condensed-matter systems; • Stability, scalability, and reproducibility of transition-metal doping strategies. By bringing together researchers working across condensed-matter physics, materials science, nanotechnology, and energy-related applications, this collection seeks to establish a comprehensive understanding of transition-metal doping as a versatile route for tuning material functionality and enabling next-generation technologies.
