| dc.description.abstract | In this study, NiO and Li0.2Ni0.8O (LNO) thin films are successfully deposited by sputtering technique. X-ray photoelectron spectroscopy (XPS) analysis revealed the existence of Ni vacancies. Here, we fabricated metal-semiconductor-metal (M-S-M) structure for exploring the ultra-violet (UV) photodetector (PD) performance. The impact of interstitial oxygen and substitutional incorporation of monovalent Li+ ion in Ni2+ sites of NiO on UV photodetector performance are explored. In a word, LNO exhibited superior responsivity (0.218 A/W) and detectivity (0.467 × 1012 Jones) even at lower power density of 0.31 mW/cm2. © 2021 Elsevier B.V. | - |
