Controlling the Morphology of Tellurene for a High-Performance H₂S Chemiresistive Room-Temperature Gas Sensor.

ABSTRACT: A two-dimensional (2D) van der Waals material composed only of tellurium (Te) atoms-tellurene-is drawing attention because of its high intrinsic electrical conductivity and strong interaction with gas molecules, which could allow the development of high-performance chemiresistive sensors. However, the correlation between the morphologies and gas detection properties of tellurene has not yet been studied in depth, and few reports exist on tellurene-based hydrogen sulfide (H₂S) chemiresistive sensors in spite of their strong interaction with H₂S molecules. Here, we investigate the morphology-dependent H₂S gas detection properties of tellurene synthesized using a hydrothermal method. To tailor the morphologies of tellurene, the molecular weight of the surfacta
