The growth and structural/optical properties of metal-oxide semiconductor nanostructures by a simple, low-cost, and large-scalable fabrication method were studied. These nanostructures were applied to energy and optoelectronic devices, such as piezoelectric nanogenerators and photodetective sensors, to improve the device performance. The morphologies and crystallinity of the fabricated nanostructures were observed from scanning electron microscope/transmission electron microscope images, respectively. The piezoelectric output current and photoresponse property were characterized by manufacturing the nanogenerators and photodetectors with prepared metal oxide nanostructures. These results can provide a fundamental understanding of the mechanisms for improving the device performance in applications of metal-oxide semiconductor nanostructures for energy and sensing devices.
