On page 700, size‐dependent optical absorption of boron‐hyperdoped silicon nanocrystals (NCs) is investigated by X. D. Pi, D. Yang, and co‐workers. For small NC sizes, the quantum confinement effect and the dielectric constant of Si NCs can cause a blue shift of the infrared absorption. This blue shift is induced by the localized surface plasmon resonance (LSPR) of Si NCs. For extremely small NC sizes, the significant scattering of free carriers at the NC surface can completely damp the LSPR.
