Development of a two-phase structural and optical model for understanding the fundamental electrochromic processes in amorphous tungsten oxide thin films

The evolution of a dense columnar morphology with a related void network structure is a natural result of random ballistic aggregation of atoms during the thin film growth process under low adatom mobility conditions. Thin film properties and applications (e.g. magneto-optic materials and a-Si:H solar cells) are often dominated by this anisotropic morphology. Electrochromism is a phenomenon in which the optical properties of a material change due to the stimulus of an applied electric field. Tungsten oxide (WO;Amorphous WO...
