| Abstract: | Self-organized nanoporous oxide layers were grown on a W-Ta alloy by electrochemical anodization. These nanostructured mixed oxide layers show an ultra-fast electrochromic switching kinetics. Compared with porous WO(3) nanostructures more than 10 times higher switching frequencies are reached along with a significantly enhanced lifetime and cyclability. |
