Oxygen vacancy formation and electronic reconstruction in strained LaNiO${}_3$ and LaNiO${}_3$/LaAlO${}_3$ superlattices

Benjamin Geisler, Simon Follmann, Rossitza Pentcheva

By using DFT+U, we explore the formation of oxygen vacancies and their impact on the electronic and magnetic structure in strained bulk LaNiO3 and (LaNiO3)${}_1$/(LaAlO3)${}_1$(001) su…
