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…
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…
Two-Level Systems in Evaporated Amorphous Silicon
D. R. Queen, X. Liu, J. Karel +3
In -beam evaporated amorphous silicon (-Si), the densities of two-level systems (TLS), and , determined from specific heat and internal friction $Q^…
