Semiconductor nanostructured materials have superior performances far beyond those of their bulk counterparts. Despite of the potential, however, the applications of those materials are limited by their intrinsic properties. In this regard, the hybridization of different types of materials is crucial as it can enable versatile and tailor-made properties with performances far beyond those of each material. Here we present the synthesis and fabrication issues in the semiconductor nanocrystal arrays and graphene hybrid structures and the potential applications for pixel-type optoelectronic devices. We first demonstrate the step-by-step growth of hierarchical 3D architecture ZnO crystals in low temperature solution and then heteroepitaxial growth of GaN on the core ZnO templates. In addition, to create high performance or multi-functionality, we introduced semiconductor nanocrystals and graphene hybrid arrays for pixel-type optoelectronics. Our study illustrated the expendability of this work to many other materials and related device applications, such as LEDs, photodetectors, sensors, and photovoltaic cells. |
