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.

全光子相变存储器：利用金纳米粒子等离子体共振的硫属化物玻璃的低功率相变（高级光学材料6/2020）

正如Tun Cao及其同事在文章编号1901570中所显示的，一簇金纳米颗粒（Au NPs）分散在硫族化物膜上，以降低硫族化物层的相变功率。之所以降低功率，是因为通过提高了光吸收率金纳米粒子的强局部表面等离子体共振。这种设计适用于高速，低功耗的相变存储器以及新型的可调表面增强拉曼散射基板。
