Fig. 3. Schematic of the fabrication process flow of flexible LEDs based on vertical nitride nanowire arrays. Panels (a–c) illustrate the fabrication steps for semitransparent LEDs with Ti/Au and Ag nanowires as the back and top contacts, respectively. (d) Photograph of a semitransparent LED. Panels (e–g) show the process of fully transparent LEDs with Ag nanowires as both back and top contacts. (h) Photograph of a transparent LED. Adapted with permission from ref. 58.
