Thermal bolometers are bulky and slow, whereas electronic terahertz detectors (such as Schottky diodes) are fast, but their sensitivity degrades quickly outside a narrow frequency window. Here, we show that a two-dimensional correlated topological semimetal, tantalum iridium telluride (TaIrTe4), has a large room-temperature nonlinear Hall effect and that the interaction between this effect and terahertz nonlinear electrodynamics can be used as a mechanism for terahertz sensing. Our photodetectors exhibit a high sensitivity (noise-equivalent power of around 1 pW Hz−1/2) and a large zero-bias responsivity (around 0.3 A W−1) over a broadband spectral range (0.1–10 THz) at room temperature with an intrinsic ultrafast response time (picoseconds). The zero-bias responsivity and noise-equivalent power performance can be further improved (to 18 A W−1 and 0.05 pW Hz−1/2, respectively) by introducing gate-tunable electron correlations. description_type: abstract lang: en ## Creator - name: Tairan Xi role: author - name: Haotian Jiang role: author - name: Jiangxu Li role: author - name: Yangchen He role: author - name: Yuchen Gu role: author - name: Carter Fox role: author - name: Louis Primeau role: author - name: Yulu Mao role: author - name: Jack Rollins role: author - name: Takashi Taniguchi role: author orcid: https://orcid.org/0000-0002-1467-3105 organization: National Institute for Materials Science - name: Kenji Watanabe role: author orcid: https://orcid.org/0000-0003-3701-8119 organization: National Institute for Materials Science - name: Daniel van der Weide role: author - name: Daniel Rhodes role: author - name: Yang Zhang role: author - name: Ying Wang role: author - name: Jun Xiao role: author ## Contact agent ## Publisher organization: Springer Science and Business Media LLC ## Managing organization ## Keyword - subject: Terahertz detection schema: not_defined - subject: Nonlinear Hall effect schema: not_defined - subject: Topological semimetal schema: not_defined ## Rights - description: 'This version of the article has been accepted for publication, after peer review (when applicable) and is subject to Springer Nature’s AM terms of use, but is not the Version of Record and does not reflect post-acceptance improvements, or any corrections.
