Thermal conductivity of amorphous solids

Physical Review B, 1986
The thermal conductivities of glassy solids, when scaled by material parameters, have a similar magnitude and temperature dependence, from the lowest temperatures yet measured, to the melt. Both empirical results and theoretical models are reviewed briefly.

Anharmonic solids. Thermal conductivity

Bulletin de la Classe des sciences, 1960
Using a method developed by Prigogine and Henin the thermal conductivity of an anharmonic crystal is obtained to the order λ2. The calculation is performed using the « brownian motion assumption » wich enables us to get results solving relatively simple equations — a correction due to dilatation effects is also included.

Thermal conductivity of solid oxygen

Physical Review Letters, 1993
This paper reports the results of the first measurements of the thermal conductivity of the \ensuremath{\alpha}, \ensuremath{\beta}, and \ensuremath{\gamma} phases of solid oxygen over the temperature range of 1--52 K. A simple qualitative analysis was performed to explain the observed anomalies in thermal conductivity, which manifested themselves by a

Thermal conductivity of solid nitrogen

Physical Review B, 1994
Thermal conductivity of crystalline natural nitrogen was investigated over the temperature range 1.2--38 K. The temperature dependence of thermal conductivity of \ensuremath{\alpha}-nitrogen has been determined in temperatures below 18 K. The thermal conductivity coefficient reaches the maximum value 250 mW/cm K at 3.6 K.

Thermal conductivity of disordered harmonic solids

Physical Review B, 1993
As a crystal is disordered, a point may be reached where the typical mean free path of phonons is so short that the wavelength and mean free path are no longer sharp concepts, and the textbook phonon-gas model for thermal conductivity breaks down. This paper proposes an alternate theory for the disordered regime, and the subsequent paper implements the

Effect of strain on the thermal conductivity of solids

The Journal of Chemical Physics, 2006
We present a systematic study of the effect of strain (equivalent to uniform pressure) on the thermal conductivity of an insulating solid. Following a theoretical analysis that uncovers the dependence of the thermal conductivity on temperature and strain, we present classical molecular dynamics calculations of the thermal conductivity. We find that the

Thermal Conductivity of Solid Ammonia

physica status solidi (b), 1968
AbstractThe thermal conductivity of solid ammonia is measured by the linear stationary method with continuous visual control of the sample state. The measurements are carried out in the temperature range 28 to 114°K. The temperature dependence of the thermal conductivity is discussed.
