Defect-Mediated Electronic Structure in Ag2CrO4: From Electronic Structure and Bonding Analysis to Optical, Magnetic, and Transport Responses

Silver chromate (Ag2CrO4) was synthesized via a microwave-assisted hydrothermal route to elucidate how defect-mediated structural distortions govern its multifunctional properties. X-ray diffraction and Rietveld refinement suggest a phase-pure orthorhombic structure, while selected-area electron diffraction (SAED) an...

Oxygen-Vacancy-Controlled Band-Gap Engineering in Fe/Co Co-doped La-Modified Bismuth Titanate: Integrated Experimental and First-Principles Analysis

Layered Aurivillius ferroelectrics offer a route to multifunctional band-gap engineering, yet the role of oxygen vacancies in band-edge reconstruction in Fe/Co-modified compositions remains poorly resolved. Here, oxygen annealing of Bi3.25La0.75Ti2.60(Fe0.50,Co0.50)0.40O12 (BLFC4) ceramics widens the optical band gap b...
