Anisotropic Effects of Oxygen Vacancies on Electrochromic Properties and Conductivity of $\gamma$-Monoclinic WO${}_3$

Matteo Gerosa, Cristiana Di Valentin, Giovanni Onida +2

Tungsten trioxide (WO${}_3$) is a paradigmatic electrochromic material, whose peculiar optical properties in the presence of oxygen vacancies or intercalated alkali atoms have been o…
