Temperature effects on the structure and mechanical properties of vapor deposited a-SiO2
Vrishank Jambur, Manel Molina-Ruiz, Tom Dauer +7
Amorphous silica (a-SiO2) exhibits unique thermo-mechanical behaviors that set it apart from other glasses. However, there is still limited understanding of how this mechanical beh…
Structural tunability and origin of two-level systems in amorphous silicon
H. C. Jacks, M. Molina-Ruiz, M. H. Weber +5
Amorphous silicon films prepared by electron beam evaporation have systematically and substantially greater atomic density for higher thickness, higher growth temperature, and slow…
Decoupling between propagating acoustic waves and two-level systems in hydrogenated amorphous silicon
M. Molina-Ruiz, H. C. Jacks, D. R. Queen +3
Specific heat measurements of hydrogenated amorphous silicon prepared by hot-wire chemical vapor deposition show a large density of two-level systems at low temperature. Annealing…
Origin of Mechanical and Dielectric Losses from Two-Level Systems in Amorphous Silicon
M. Molina-Ruiz, Y. J. Rosen, H. C. Jacks +5
Amorphous silicon contains tunneling two-level systems, which are the dominant energy loss mechanisms for amorphous solids at low temperatures. These two-level systems affect both…
A 10 mK hermetic cell for eliminating parasitic heating in cryogen-free dilution refrigerators
David Schmoranzer, Sumit Kumar, Sébastien Triqueneaux +5
Cryogen-free dilution refrigerators generally simplify low temperature research but some types of samples, including superconducting qubits and other nanoelectronic devices, are af…
Dielectric loss extraction for superconducting microwave resonators
C. R. H. McRae, R. E. Lake, J. L. Long +6
The investigation of two-level-state (TLS) loss in dielectric materials and interfaces remains at the forefront of materials research in superconducting quantum circuits. We demons…
