On page 2504, C.‐H. Cho and co‐workers present a diameter‐modulated semiconductor nanowire array to enhance optical absorption across a broad spectral range. The periodicity in the diameter of the silicon nanowires enables stronger and more closely spaced optical resonances, leading to broadband absorption enhancement. This study highlights tailored light–matter interactions by periodic shape engineering for high‐performance optoelectronic devices.
