TLDR
In this paper, a linear temperature dependence of the specific heat in amorphous solids at very low temperatures is shown to follow from an ionic tunneling model, which predicts both the observed temperature dependence and the magnitude of the thermal conductivity.
Abstract
A linear temperature dependence of the specific heat in amorphous solids at very low temperatures is shown to follow from an ionic tunneling model. Moreover, this model predicts both the observed temperature dependence and the magnitude of the thermal conductivity and also explains the anomalous results obtained for the phonon free path by means of stimulated Brillouin scattering.

A.c. conduction in amorphous chalcogenide and pnictide semiconductors

TL;DR: In this article, a comprehensive survey is given of the experimental a.c. data for two types of amorphous semiconductor, namely chalcogenide and pnictide materials, and it is concluded that the behavior at intermediate to high temperatures is well accounted for by the correlated-barrier-hopping model, whereas the low-temperature behaviour is probably due to atomic tunnelling.

Continuous deformations in random networks

TL;DR: In this paper, the authors examine the differences between covalent random networks with high and low average coordination and make rigorous assumptions about the number of continuous deformations (i.e., zero frequency modes) allowed within the network.

Noise in solid-state microstructures: A new perspective on individual defects, interface states and low-frequency (1/ƒ) noise

TL;DR: In very small electronic devices, the alternate capture and emission of carriers at an individual defect site generates discrete switching in the device resistance, referred to as a random telegraph signal (RTS) as mentioned in this paper.

Thermal Conductivity and Specific Heat of Noncrystalline Solids

TL;DR: The thermal conductivity of vitreous Si, Se, and silica-and germania-based glasses has been measured between 0.05 and 100 \ifmmode^\circ\else\text degree\fi{}K, suggesting a Rayleigh-type scattering mechanism as mentioned in this paper.
