Ab initio based thermal property predictions at a low cost : an error analysis [PDF]

, 2014
Ab initio calculations often do not straightforwardly yield the thermal properties of a material yet. It requires considerable computational efforts, for example, to predict the volumetric thermal expansion coefficient alpha(V) or the melting temperature

Thermal expansion coefficients of graphite crystals [PDF]

Carbon, 1972
Abstract Graphite crystal expansions were derived as a function of temperature using the theoretical relationships of Riley; the resultant equations provide reasonable fits to the measured lattice expansion data over the temperature range 300–3000 ...

Thermal contraction in silicon nanowires at low temperatures

, 2010
The thermal expansion effect of silicon nanowires (SiNW) in [100], [110] and [111] directions with different sizes is theoretically investigated. At low temperatures, all SiNW studied exhibit thermal contraction effect due to the lowest energy of the ...
