Authors: P K Shihabudeen, Alex Sam, Shih-Wen Chiu, Ta-Jen Yen, Kea-Tiong Tang

Abstract: Niobium disulfide (NbS2), a two-dimensional transition metal dichalcogenide with semi metallic conductivity and high surface activity, offers promising properties for electronic and sensing applications. In this study, we report a high-performance NO2 gas sensor based on a heterostructure comprising a spin-coated In2O3 film on a semi-metallic NbS2 film.
