In this work, density functional calculations and Boltzmann semiclassical theory of transport are used to investigate structural, electronic, and thermoelectric properties of AgSbSe2 crystal. According to the published experimental measurements, five more likely structures of this compound are considered and their structural and electronic properties are calculated and compared together. Then, ...
We have calculated the electronic structure of Sr2RuO4 using the full potential linearized augmented plane wave method in the spin polarized local density approximation. By this calculation, we identify the contribution of different electronic states near Fermi surface and study some electronic parameters like crystal electric field, exchange splitting, and hybridization between different atoms...
Transport measurements are powerful tools to probe electronic properties of solid-state materials. To access properties of local electronic states in nanostructures, such as local density of states, electronic distribution and so on, micro-probes utilizing artificial nanostructures have been invented to perform measurements in addition to those with conventional macroscopic electronic reservoir...
We consider lattice dynamics with a small stochastic perturbation of order ε and prove that for a space-time scale of order ε the local spectral density (Wigner function) evolves according to a linear transport equation describing inelastic collisions. For an energy and momentum conserving chain the transport equation predicts a slow decay, as 1/ √ t, for the energy current correlation in equil...
well-defined crystalline pbse nanocubes and nanospheres have been synthesized through a simple hydrothermal method by using pb2+- edta and pb2+- oleylamine complexes at 180°c for different reaction times. composition and morphology of the samples have been characterized by means of xrd and sem. gradual release process of pb2+ from pb2+-edta and pb2+-oleylamine complexes can adjust the growth ra...

We consider the problem of estimating a probability density function based on data that are corrupted by noise from a uniform distribution. The (nonparametric) maximum likelihood estimator for the corresponding distribution function is well defined. For the density function this is not the case. We study two nonparametric estimators for this density. The first is a type of kernel density estima...
