One-dimensional nanostructures for photodetectors

With large surface-to-volume ratios and Debye length comparable to their small size, one-dimensional nanostructures have been extensively studied and have been widely used to fabricate many high-performance and new type nanoscale electronic and optoelectronic devices. In this work, we provide a comprehensive review on the state-to-the-art research activities on the photodetectors application of one-dimensional nanostructures. The review begins with a survey of the patents and reports on the synthesis of one-dimensional nanostructures, which can be used to fabricate photodetectors. Then the recent progress on this topic is discussed, focusing on 1-D metal oxide, III-V group semiconductors, and other nanomaterials. This review will then be finalized with some perspectives and outlook on the future developments of this research topic.
