Spintronic and electrochromic device based on Li-intercalated transition-metal doped anatase $\mathrm{Ti}{\mathrm{O}}_2$

Abstract

We have explored the effects of the Li intercalation on the electronic and magnetic properties of transition-metal (TM) doped anatase TiO${}_2$. By Li intercalation, Mn-doped TiO${}_2$ exhibits the insulator to metal transition. On the other hand, Li-intercalated Fe-doped TiO${}_2$ has the insulating ground state for low concentration of Li/Ti=0.067, but the metallic ground state for high concentration of Li/Ti=0.133. We discuss the $n$-type carrier induced ferromagnetism in Li-intercalated TM-doped anatase TiO${}_2$. Based on the Li-intercalated TM-doped anatase TiO${}_2$, we propose a potential spintronic and electrochromic device controlled by the electric-field.
