Abstract
Wedeveloped hybrid superconducting microwave resonators incorporating van der Waals (vdW) superconductors to explore the microwave response of superconducting 2D materials in the GHz regime. We first established a reliable technique to contact thin NbSe₂, entirely encapsulated with hexagonal Boron Nitride (hBN), with a coplanar Al resonator. Then we fabricated hybrid Al-NbSe₂ resonators and measured the kinetic inductance of thin NbSe₂ at low-temperature and low-photon number limits. In this thesis, we discuss the observed relation between the kinetic inductance and the thickness of the thin NbSe₂. Furthermore, we characterize DC bias current, and microwave power dependence of the kinetic inductance in the hybrid Al-NbSe₂ resonators. Our approach contributes to understanding the both DCand ACproperties of superconducting 2D materials with potential implications for their utilization in emerging technologies.
