N2 - Developing multiple functionalities in nanodevices is a desirable objective in current nanotechnology, where the self-powered capability is one of the most demanded functions—without the need of external batteries, nanodevices can be operated independently and maintenance-free for a long period of time. In this study, we fabricated the core-shell nanostructured device employing multi-walled carbon nanotubes (CNTs) as inner cores and ZnO as outer shells, and demonstrate their multiple functionalities of fast UV detection and self-powered capability. The device features high photoconductive gain of 800 and short response time of 0.48 ms in air and 29 ms in vacuum. For energy harvesting, the device shows photovoltaic (PV) capability to drive a conventional liquid crystal display (LCD) with a Voc of 0.85V and Isc of 5nA. Those features demonstrate that our CNT-ZnO core-shell nanostructured device, performing both high photoresponsivity and PV capability, can be operated in different functionalities with or without external bias.
