Abstract
Superconducting transition-edge sensors (TES) have emerged as fascinating devices to detect broadband electromagnetic radiation with low thermal noise. The advent of metallic transition metal dichalcogenides, such as NbSe2, has also created an impetus to understand their low-temperature properties, including superconductivity. Interestingly, NbSe2-based sensor within the TES framework remains unexplored. In this work, direct-probed superconducting NbSe2 absorbers led to a proof-of-concept demonstration for the transduction of incoming light to heat, where a thermodynamic superconducting phase transition in NbSe2 was evident to switch it to the normal-state, when biased below its superconducting transition temperature. A wavelength-dependent response of its optical absorption properties was observed, based on the incident optical excitation source used. Furthermore, extensive optical characterization studies were conducted using Raman spectroscopy, where the in-plane and out-of-plane thermal conductivity was empirically determined. Our results open possibilities for the use of NbSe2 in superconducting radiation detectors, including in a TES framework.
