Briefings

This study investigates neon thin films using a high-$T_c$ YBCO resonator near the triple point. Liquid neon films exhibit rich dynamics including uniform wetting saturating at 20 nm, drainage of thicker films, and spontaneous thickness oscillations. Freezing these films reveals solid thickness variations of approximately an order of magnitude. The addition of neon increases the quality factor by a factor of 1000, ruling out dielectric loss as the limiting factor. The research demonstrates that hermetic packaging enables investigation of non-equilibrium fluid dynamics but may not be optimal for growing solid neon films with precise thickness control.

Key points

• Liquid neon films near the triple point exhibit spontaneous thickness oscillations and uniform wetting saturating at 20 nm.
• Freezing neon across various liquid levels results in solid film thickness variations of approximately an order of magnitude.

Context

Researchers monitor neon films near the triple point using a multimode resonator fabricated from high-$T_c$ YBCO. This setup allows observation of liquid phase dynamics and electrostatic tuning of film thickness, providing insights into how condensed noble gases interact with superconducting circuits.

Limitations

The evidence is limited to observations of liquid and frozen neon films. The study does not provide data on the growth process of solid neon films, nor does it offer a definitive conclusion on whether hermetic packaging is the best modality for precise solid film growth.
