Hydrogen-free amorphous silicon with no tunneling states.

@article{Liu2014HydrogenfreeAS,  title={Hydrogen-free amorphous silicon with no tunneling states.},  author={Xiao Liu and D. R. Queen and Thomas Harker Metcalf and Julie E. Karel and Frances Hellman},  journal={Physical review letters},  year={2014},  volume={113 2},  pages={          025503        },  url={https://api.semanticscholar.org/CorpusID:20919532}}
This work obviates the role hydrogen was previously thought to play in removing TLSs in the hydrogenated form of a-Si and suggests it is possible to prepare "perfect" amorphous solids with "crystal-like" properties for applications.

Two-level systems and growth-induced metastability in hydrogenated amorphous silicon

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, significantly larger…

Elastic Measurements of Amorphous Silicon Films at mK Temperatures

The low-temperature properties of glass are distinct from those of crystals due to the presence of poorly understood low-energy excitations. The tunneling model proposes that these are atoms…

Origin of mechanical and dielectric losses from two-level systems in amorphous silicon

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 mechanical and…

Manipulation of Glassy State in Amorphous Selenium by Low-temperature Internal Friction Measurements

We have studied the thickness and quench-rate dependent internal friction of amorphous selenium (a-Se) thin films deposited at room temperature. The internal friction of a-Se films exhibit a…

Light-induced metastability in pure and hydrogenated amorphous silicon

Light soaking is found to increase the specific heat C and internal friction of pure (a-Si) and hydrogenated (a-Si:H) amorphous silicon. At the lowest temperatures, the increases in C and are…

Effect of Deep-Defects Excitation on Mechanical Energy Dissipation of Single-Crystal Diamond.

The deep energy nature of the defects bestows single-crystal diamond with outstanding low intrinsic energy dissipation in mechanical resonators at room temperature or above.

Depletion of Two-Level Systems in Ultrastable Computer-Generated Glasses.

It is found that as the stability of a glass increases, its energy landscape as well as the manner in which it is probed tend to deplete the density of tunneling defects, as observed in recent experiments.

Low-temperature anomalies of a vapor deposited glass

We investigate the low temperature properties of two-dimensional Lennard-Jones glass films, prepared in silico both by liquid cooling and by physical vapor deposition. We identify deep in the solid…
