Strongly enhanced light trapping in a two-dimensional silicon nanowire random fractal array

Abstract We report on the unconventional optical properties exhibited by a two-dimensional array of thin Si nanowires arranged in a random fractal geometry and fabricated using an inexpensive, fast and maskless process compatible with Si technology. The structure allows for a high light-trapping eff...
