Transferable silicon nanowire arrays embedded in flexible polymer for color tuning with metal insulator metal structure

Abstract

Yeong Jae Kim Young Jin Yoo Gil Ju Lee Dong Eun Yoo Dong Wook Lee, Vantari Siva, Hansung Song, Il Suk Kang, Young Min Song Here, we present the transferable color-tuning structures. These structures are comprised of a polymer embedded silicon nanowire arrays (Si NWAs) stacked on a metal/insulator/metal (MIM) cavity. Upon stacking the Si NWAs on the MIM cavity, these cyan, magenta and yellow colors can be tuned to a color gamut by varying parameters of the Si NWAs such as diameter, height and periods. The fine tuning of these colors were explained on the basis of the measured reflectance spectra, which was further supported by the theoretical simulations.
