Abstract

Abstract : A cluster of gold nanoparticles (Au NPs) is dispersed on chalcogenide film to reduce the phase transition power of the chalcogenide layer, as shown by Tun Cao and co‐workers in article number 1901570 . This reduced power is owing to the enhanced light absorptance through the strongly localized surface plasmon resonance of the Au NPs. Such a design is suitable for high‐speed, low‐power phase‐change memory and for a new type of tunable surface‐enhanced Raman scattering substrate.
