Abstract:Lanthanum nickelate (LaNiO 3 ) is a promising material for stable fuel-cell electrode, optoelectronic and magneto-electronic devices. Density functional theory (DFT) based calculations were carried out to investigate the effect of strain on the physical properties of the correlated metal LaNiO 3 . Electronic structure, optical conductivity and temperature variation of resistivity have been studied in detail using GGA+U approach. It has been observed that LaNiO 3 under strain is more metallic compared to the un… Show more
