摘要: A diameter-modulated silicon nanowire array to enhance the optical absorption across broad spectral range is presented. Periodic shape engineering achieved using conventional semiconductor processes and unique properties are analyzed. The periodicity in diameter of nanowires enables stronger more closely spaced resonances, leading broadband enhancement.
