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…
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…
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 Cryogenic Silicon Interferometer for Gravitational-wave Detection
Rana X Adhikari, Odylio Aguiar, Koji Arai +108
The detection of gravitational waves from compact binary mergers by LIGO has opened the era of gravitational wave astronomy, revealing a previously hidden side of the cosmos. To ma…
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…
