Off-Resonant Absorption Enhancement in Single Nanowires via Graded Dual-Shell Design

Off-Resonant Absorption Enhancement in Single Nanowires via Graded Dual-Shell Design

Single nanowires (NWs) are of great importance for optoelectronic applications, especially solar cells serving as powering nanoscale devices. However, weak off-resonant absorption can limit its light-harvesting capability. Here, we propose a single NW coated with the graded-index dual shells (DSNW)....
