A resonant cavity is designed in the shape of a multishelled spherical structure by Dan Wang, Jr‐Hau He, Yi Cui, and co‐workers in article number 1801972. Due to the resonance‐enhanced absorption by multiple convex shells, fabricated metal oxide photodetectors show improved optoelectronic performance and omnidirectional detection of light at different incident angles and polarization. The optical...
Optical resonance formed inside a nanocavity resonator can trap light within the active region and hence enhance light absorption, effectively boosting device or material performance in applications of solar cells, photodetectors (PDs), and photocatalysts. Complementing conventional circular and spherical structures, a new type of multishelled spherical resonant strategy is presented. Due to the resonance‐enhanced...
