Tailoring the structural, electronic, mechanical, and optical properties of SrTiO3 via 7% Cu doping at the Ti site: A comprehensive DFT study
Strontium titanate (SrTiO3) is a wide-band-gap (~3.2 eV) perovskite oxide semiconductor with a high dielectric constant and excellent thermal and chemical stability, properties that have made it attractive for photocatalysis, photovoltaics, sensors, and electronic devices. Its large band gap, however, restricts light a...
