Description
Peng Su, Si-Han Lin, and Fang-Xing Xiao design in 2026 a light-harvesting assembly where the wrapping on metal particles boosts electron tunneling through an insulating film. Classic designs sandwich a plain insulator between a semiconductor and a metal. Here a thin charged polymer coats light-absorbing crystals, and polymer-wrapped gold or palladium particles dock onto it by static attraction.
The wrapping is not passive: it couples with its metal core to form a joint electron trap that pulls charge hard. That pull drives electrons through the insulating layer from the excited crystal, bypassing the usual energy barrier. The assemblies then drove selective chemical conversions and hydrogen peroxide production under visible light more effectively. The authors offer the design as a new handle for programming charge flow in artificial photosynthesis.
