Superconducting Properties of Atomically-Thin NbSe2 Sheets

The superconducting members of the transition metal dichalcogenides (TMDCs) family display unique superconducting properties arising from broken in-plane mirror symmetry and multiply occupied bands. Here, we report on device fabrication and low-temperature transport measurements of atomically-thin sheets of superconducting NbSe2. Deviations from conventional I-V curves and anomalous RF responses are observed and discussed in the context of superconducting behavior predicted for this material.
