Abstract
A nano-structured light-emitting device includes a plurality of light-emitting nanostructures each having a resistant layer disposed thereon. The device includes a first semiconductor layer of a first conductivity type, and a plurality of nanostructures disposed on the first semiconductor layer. Each nanostructure includes a nanocore, and an active layer and a second semiconductor layer of a second conductivity type that enclose surfaces of the nanocores. An electrode layer encloses and covers the plurality of nanostructures A plurality of resistant layers are disposed on the electrode layer and each corresponds to a respective nanostructure of the plurality of nanostructures.
