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…
Strategies to reduce the thermoelastic loss of multimaterial coated finite substrates
Ruinan Zhou, Manel Molina-Ruiz, Frances Hellman
Thermoelastic loss is an important energy dissipation mechanisms in resonant systems. A careful analysis of the thermoelastic loss is critical to the design of low-noise devices fo…
Compositional Trends in Surface Enhanced Diffusion in Lead Silicate Glasses
Ajay Annamareddy, Manel Molina-Ruiz, Donez Horton-Bailey +4
In this work, we use molecular dynamics simulations to study the enhancement of surface over bulk diffusion (surface enhanced diffusion) in (PbO)x(SiO2)1-x glasses. This work is mo…
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…
Observation of spin-momentum locked surface states in amorphous BiSe
Paul Corbae, Samuel Ciocys, Daniel Varjas +12
Crystalline symmetries have played a central role in the identification of topological materials. The use of symmetry indicators and band representations have enabled a classificat…
Two-level systems and growth-induced metastability in hydrogenated amorphous silicon
M. Molina-Ruiz, H. C. Jacks, D. R. Queen +3
Specific heat measurements from 2 to 300 K of hydrogenated amorphous silicon prepared by hot-wire chemical vapor deposition show a large excess specific heat at low temperature, si…
