Quasi-elastic light scattering from individual electron single-particle excitations is observed experimentally and studied theoretically in n-GaAs and n-InP samples with nonparabolic dispersion of energy bands for a wide range of free-electron concentrations varying from ≈108 to ≈1019 cm-3. The results indicate that the scattering mechanisms associated with charge-, spin- and momentum-density fluctuations are represented by different light scattering line shapes and occur in different concentration ranges. 相似文献

In this paper, we investigate uniform convergence of the improper Hubbell radiation rectangular source (HRS) integral H(a,b). We prove that HRS integral H(a,b) is uniform convergent in the domain D?{(a,b)∈[0,A]×[0,∞)} for any positive finite number A. Then we give an accurate and efficient computation algorithm for the HRS integral. 相似文献

A system with n independent components which has a k-out-of-n: G structure operates if at least k components operate. Parallel systems are 1-out-of-n: G systems, that is, the system goes out of service when all of its components fail. This paper investigates the mean residual life function of systems with independent and nonidentically distributed components. Some examples related to some lifetime distribution functions are given. We present a numerical example for evaluating the relationship between the mean residual life of the k-out-of-n: G system and that of its components. 相似文献

Di(4-isopropenylphenoxy)alkanes were synthesized by condensation of 4-isopropenylphenol with symmetrical dihaloalkanes in the presence of KI promoter. Three-dimensional polymeric structures were prepared by compolymerization of these monomers with styrene. 相似文献

Spectra of inelastic light scattering by optical phonons in p-CdGeAs2 single crystals were obtained for the first time. The observed clear polarization dependence and the absence of any appreciable
dependence of the intensity and frequency of the observed lines when the sample is swept in ≈300 μm steps indicates these
CdGeAs2 single crystals grown by directional crystallization from a near-stoichiometric flux, are of high quality and homogeneous.
The type of symmetry of the observed phonon lines is interpreted and it is shown that the force constants in CdGeAs2 and CdSnP2 crystals differ slightly. Temperature dependences of the electrical conductivity and the Hall constant were studied in oriented
homogeneous p-CdGeAs2 single crystals. It was established that the conductivity of these crystals is determined by the deep acceptor level E
A=0.175 eV and has the degree of compensation 0.5–0.6. The temperature dependence of the Hall mobility reflects the competition
between impurity and lattice mechanisms of hole scattering. The photosensitivity of In/CdGeAs2 surface barrier structures reaches 20 μA/W at T=300 K and remains at this level within the fundamental absorption of CdGeAs2. It is concluded that these structures may be used as wide-band photoconverters for natural light and as selective photoanalyzers
for linearly polarized radiation.

Angular dependences of resonance field and linewidth have been measured for ferromagnetic CdCr2Se4 crystal doped with 1.5 mol.% Ag before and after annealing in vacuum. The change of the sign of anisotropy due to annealing is associated with transformations Cr4+→Cr3+→Cr2+. On the basis of obtained data some suppositions are made about the mechanisms of conductivity in the Ag-doped CdCr2Se4 crystal. 相似文献
