There has been much research interest in the development of metal oxide-based UV photodetectors. In this work, a nano-interlayer was introduced in a metal oxide-based heterojunction UV photodetector to enhance the rectification characteristics and therefore the device performance. The device, which consists of nickel oxide (NiO) and zinc oxide (ZnO) sandwiching an ultrathin dielectric layer of titanium dioxide (TiO2), was prepared by radio frequency magnetron sputtering (RFMS). After annealing, the NiO\/TiO2\/ZnO UV photodetector exhibited a rectification ratio of 104 under UV irradiation of 365 nm at zero bias. The device also demonstrated a high responsivity of 291 A\/W and a detectivity of 6.9 \u00d7 1011 Jones at +2 V bias. Such a device structure provides a promising future for metal oxide-based heterojunction UV photodetectors in a wide range of applications.<\/jats:p>","DOI":"10.3390\/s23052741","type":"journal-article","created":{"date-parts":[[2023,3,2]],"date-time":"2023-03-02T04:57:38Z","timestamp":1677733058000},"page":"2741","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["High-Performance NiO\/TiO2\/ZnO Photovoltaic UV Detector"],"prefix":"10.3390","volume":"23","author":[{"given":"Guoxin","family":"Shang","sequence":"first","affiliation":[{"name":"School of Materials and Energy, Yunnan University, Kunming 650500, China"},{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Libin","family":"Tang","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gang","family":"Wu","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shouzhang","family":"Yuan","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Menghan","family":"Jia","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"},{"name":"School of Physics and Astronomy, Yunnan University, Kunming 650500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaopeng","family":"Guo","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Zheng","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Biao","family":"Yue","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kar Seng","family":"Teng","sequence":"additional","affiliation":[{"name":"Department of Electronic and Electrical Engineering, Swansea University, Bay Campus, Fabian Way, Swansea SA1 8EN, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1700264","DOI":"10.1002\/adfm.201700264","article-title":"An Ultrahigh Responsivity (9.7 mA W\u22121) Self-Powered Solar-Blind Photodetector Based on Individual ZnO-Ga2O3 Heterostructures","volume":"27","author":"Zhao","year":"2017","journal-title":"Adv.
