Patent ID: 8097879

Claim:
A light emitting diode (LED), for broadband emission of light having a wavelength between 200 nm and 700 nm, comprising: at least one p-doped structure; a plurality of low-temperature growth n-doped zinc-oxide (ZnO) nanowires that are uniformly doped on the at least one p-doped structure, thereby forming a plurality of p-n junctions; at least one insulating structure arranged among the plurality of low-temperature growth n-doped ZnO-nanowires that are uniformly doped, to electrically separate the plurality of p-n junctions; and a transparent conductive layer, arranged on the at least one insulating structure and in electrical contact with the plurality of low-temperature growth n-doped ZnO-nanowires that are uniformly doped, to enable application of a voltage over the plurality of p-n junctions, thereby enabling emission of light.
