“…Furthermore, lithium ion migration during plasma processes may cause a non-uniform surface charge density and a partial extraction of injected charges from the electrochromic structure, all of which reduce device performance. The modification of the total inserted charge may induce a degradation of the device optical properties (optical modulation, optical density) and the coloration cycling reversibility [14,30].…”

“…For electrochromic material applications, it is highly desirable that WO 3 film has a rough and porous surface structure, so that it is more conducive to the intercalation and de-intercalation of proton during the electrochromic process, thus minimizing the time of optical modulation. [12][13][14] Therefore, it is of interest to determine methods to improve the surface porosity of the sputtered WO 3 film to obtain good electrochromic performance. In this paper, we thoroughly investigate the correlation between the substrate-target distance and the optical-switching capability, and demonstrate that the electrochromic performance of WO 3 films can be dramatically improved by adjusting the target-substrate distance.…”

In this paper, the correlation between the electrochromic performance and the surface morphology of the tungsten trioxide (WO 3 ) thin films sputtered by dc reactive magnetron sputtering with widely varying target-substrate distances was investigated. It is found that the optical density change (∆OD) of films is strongly affected by the target-substrate distance. The coloration efficiency (CE) at 633 nm was also found to be sensitive to the target-substrate distance, with 16 cm 2 /C of film sputtered at 6 cm and 50 cm 2 /C at 18 cm. X-ray diffraction showed that the crystal structure of films was amorphous. By using atomic force microscope to identify the surface porosity of the sputtered WO 3 films, we found that the film at longer target-substrate distance was rough, porous, and having a cone-shaped columns morphology, thus offering a good electrochromic performance for opto-switching applications.
