Freehyphen;electron electrochromic modulation in crystalline LixWO3

摘要

The reflective and absorptive contributions to the optical modulation in sputterhyphen;deposited thin films of crystalline LixWO3have been determined as a function of lithium concentration (0x0.5). The magnitude of the reflective response increases with increasing substrate temperature (Ts) during deposition forTsle;466thinsp;deg;C. ForTs466thinsp;deg;C, the reflective component decreases. The lithium concentration dependence of the absorption coefficients supports the hypothesis that absorption in crystalline LixWO3arises from freehyphen;electron scattering.
