Measurements of Lattice Constant, Thermal Expansion, and Isothermal Compressibility of Neon Single Crystals

Elastic properties of poly(vinyldene fluoride) (PVDF) crystals: A density functional theory study

“…23,24 First, we have performed benchmark calculations using the DFT/ PBE-D2 method and four solid systems, Ne, Ar, Kr and Si, as a test bed, as both experimental and previous DFT/PBE-D2 calculation results for these elemental solids and their lattice constants are available. [28][29][30][31][32][33] As shown in the Appendix, our DFT/PBE-D2 calculations reproduce recent theoretical results for these systems very well. 32 However, one difference between DFT/PBE-D2 and DFT/PW91-vdW result of Si is found, which will be discussed below.…”

The efficiency of Interatomic Coulombic Decay in Ne clusters

“…with a numerical value of k = 187.23 using ref.s [25,24], in agreement with [21] (k: Boltzmann constant). Alternatively, the size of clusters can be estimated from the bulk-to-surface ratio of a suitable photoline [26].…”

Thermal expansion of solid neon from 1 to 15 K

“…The deviation corresponding to 0.5% 6 also is shown to emphasize the excellent (if somewhat forced) agreement of the two methods between 10 and 14 K. The deviations below 8 K are larger than the esti mated X-ray error estimate, but the X-ray results for natural neon (26) and the separated isotopes (27) are not consistent within these estimates for some temperatures below 10 K, so it is reasonable to assume that the A second problem occurs because the high heat capacities and very low thermal conductivities of the solid neon samples make it difficult to establish thermal equilibrium in the capacitance cell. The thermal equilibrium can be improved by adding exchange gas to the sample chamber, but the exchange gas introduces uncertainties in the capacitance through its dielectric constant and it affects the observed length changes through the very large compressibility of solid neon.…”
