Abstrakt: Transition metal dichalcogenides is an emerging 2D semiconducting material group which has excellent physical properties in the ultimately scaled thickness dimension. Specifically, van der Waals heterostructures hold the great promise in further advancing both the fundamental scientific knowledge and practical technological applications of 2D materials. Although 2D materials have been extensively studied for various sensing applications, temperature sensing still remains relatively unexplored. In this work, we experimentally study the temperature-dependent Raman spectroscopy and electrical conductivity of molybdenum disulfide (MoS 2 ) and its heterostructures with platinum dichalcogenides (PtSe 2 and PtTe 2 ) to explore their potential to become the next-generation temperature sensor. It is found that the MoS 2 -PtX 2 heterostructure shows the great promise as the high-sensitivity temperature sensor.
