چکیده
Magnetic-field-resilient superconducting coplanar waveguide (SCPW) resonators are essential for developing integrated quantum circuits. Molybdenum–Rhenium (MoRe), which is a disordered alloy forming highly transparent contact to the graphene and carbon nanotubes, would be promising platform realizing field-resilient SCPW combined with nano-hybrid devices. We fabricated MoRe investigated their microwave transmission characteristics varying temperature external magnetic field. The thickness of film critical parameter determining lower field, kinetic inductance, characteristic impedance resonator, resulting in drastic changes quality factor resonance frequency. obtained maximum value Qi > 104 parallel fields up B|| = 0.15 T 27-nm-thick resonator.

متن کاملSurface loss simulations of superconducting coplanar waveguide resonators
Losses in superconducting planar resonators are presently assumed to predominantly arise from surface-oxide dissipation, due to experimental losses varying with choice of materials. We model and simulate the magnitude of the loss from interface surfaces in the resonator and investigate the dependence on power, resonator geometry, and dimensions. Surprisingly, the dominant surface loss is found ...

متن کاملCo-sputtered MoRe thin films for carbon nanotube growth-compatible superconducting coplanar resonators.
Molybdenum rhenium alloy thin films can exhibit superconductivity up to critical temperatures of T(c)=15K. At the same time, the films are highly stable in the high-temperature methane/hydrogen atmosphere typically required to grow single wall carbon nanotubes. We characterize molybdenum rhenium alloy films deposited via simultaneous sputtering from two sources, with respect to their compositio...
متن کاملMiniaturized High-Temperature Superconducting Microstrip and Coplanar Waveguide Filters
Two types of miniaturized high-temperature superconducting filters are described in this paper. The first type is developed by using small-sized microstrip spiral resonators, and the second type by coplanar waveguide quarter-wavelength resonators. The filters have significantly reduced size compared with many previous HTS filters. They are designed by employing an electromagnetic simulator in c...
