On EXAFS Debye-Waller factor and recent advances.
The effects of structural and vibrational disorder on the EXAFS signals are parameterized in terms of the Debye Waller (DW) factor. Here the vibrational contribution is addressed, which for most systems can be singled out by studying the temperature dependence of the EXAFS DW factor, which corresponds to a good accuracy to the parallel mean square relative displacement (MSRD) around the inter-a...
متن کاملDebye - Waller factor measurements of solid 3 He and 4
X-ray synchrotron radiation was used to measure Debye-Waller factors of helium crystals for both He and He in both hcp and fcc phases. To our knowledge, there are no previous measurements for He. The ranges studied for He and He crystals were 11.52–12.82 and 10.95–12.13 cm, respectively, and 11.5–18.2 and 12.0–20.3 K. With small uncertainty, only a Gaussian dependence upon momentum transfer Q w...
متن کاملDebye-Waller factor of liquid silica: theory and simulation.
We show that the prediction of mode-coupling theory for a model of a network-forming strong glass former correctly describes the wave-vector dependence of the Debye-Waller factor. To obtain a good description it is important to take into account the triplet correlation function c(3), which we evaluate from a computer simulation. Our results support the possibility that this theory is able to de...
متن کاملElectron cooling and debye-waller effect in photoexcited bismuth.
By means of first principles calculations, we compute the effective electron-phonon coupling constant G(0) governing the electron cooling in photoexcited bismuth. G(0) strongly increases as a function of electron temperature, which can be traced back to the semimetallic nature of bismuth. We also use a thermodynamical model to compute the time evolution of both electron and lattice temperatures...
متن کاملDebye - Waller factor in solid 3 He and 4
The Debye-Waller factor and the mean-squared displacement from lattice sites for solid He and He were calculated with path-integral Monte Carlo at temperatures between 5 and 35 K, and densities between 38 and 67 nm. It was found that the mean-squared displacement exhibits finite-size scaling consistent with a crossover between the quantum and classical limits of N and N, respectively. The tempe...
