Abstract:
1. An optoelectronic device, comprising: a semiconductor structure combination, comprising at least one P-N junction and having an upper surface, wherein the semiconductor structure combination has a plurality of nanorods on the upper surface; a first surface passivation layer, being formed to overlay the upper surface of the semiconductor structure combination, and having a first interfacial state density and a first fixed oxide charge density; and a second surface passivation layer, being formed to directly overlay and come into contact with the first surface passivation layer, and having a second interfacial state density and a second fixed oxide charge density; wherein the first interfacial state density is lower than the second interfacial state density, and the second fixed oxide charge density is higher than the first fixed oxide charge density.
