Topological semimetal materials have garnered significant interest due to their distinctive electronic structures and unique properties. They serve as a foundation for exploring various physical phenomena including the anomalous Hall effect， topological phase transitions and negative magnetoresistance， while also offering potential solutions to the "THz Gap." This study focuses on the type-II Weyl semimetal tetratellurium iridium niobium （NbIrTe₄） terahertz detector which exhibits a responsivity of 4.36 A/W， a noise equivalent power of 12.34 pW/Hz^1/2 and an anisotropic resistance ratio of 32 at room temperature. This research paves the way for achieving high-performance terahertz detection at room temperature and serves as a reference for investigating the Weyl semimetal.
