Nanorod Array Structure Through a Nanomolding Process for Semiconductor Lighting and Display Applications

Abstract

Three-dimensional structure and growth can be more appropriately realized through a nanomanufacturing process that uses a mask patterning and etching process. Unlike conventional single-wavelength semiconductor lighting sources, the uniformity and reproducibility of the nanomolding process in this study enable multiple wavelengths to be used in lighting and display applications. This study shows the various wavelength characteristics through a newly developed nanomold and its nanorod array and also proves the feasibility of a white light without phosphors for emitting multiple wavelengths from a single chip. In this study, we proposed the possibility of wavelength control by fabricating a light-emitting diode with a three-dimensional nanostructure, using a nanomold with semiconductor processing.
