The quasimolecularKX-ray spectrum obtained by bombarding Nb with 67 MeV Nb ions has been found to undergo a Doppler shift with an effective Doppler velocity equal to the mean center-of-mass velocity of the intermediate Nb+Nb molecule, corresponding to the projectile velocity. By applying Doppler shift corrections the intrinsic anisotropy of the quasimolecularKX-radiation is found. 相似文献

It is found experimentally that the introduction of 1% Fe in the CuGeO3 matrix gives rise to a strong disorder in the magnetic subsystem and leads to an appearance of the χ~1/T α (α ≈0.36) low-temperature asymptotic form for magnetic susceptibility over a wide temperature range 1.7≤ T≤30 K. A model attributing this anomaly to the suppression of spin-Peierls state as a result of the formation of the quantum critical point is proposed. 相似文献

A study of the mechanism governing the initial stages in silicide formation under deposition of 1–10 monolayers of cobalt on a heated Si(111) 7×7 crystal is reported. The structural data were obtained by an original method of diffraction of inelastically scattered medium-energy electrons, which maps the atomic structure of surface layers in real space. The elemental composition of the near-surface region to be analyzed was investigated by Auger electron spectroscopy. Reactive epitaxy is shown to stimulate epitaxial growth of a B-oriented CoSi2(111) film on Si(111). In the initial stages of cobalt deposition (1–3 monolayers), the growth proceeds through island formation. The near-surface layer of a CoSi2(111) film about 30 Å thick does not differ in elemental composition from the bulk cobalt disilicide, and the film terminates in a Si-Co-Si monolayer triad. 相似文献

D.C. and A.C. conductivities of carbyne samples were studied over the temperature range 1.8–300 K at frequencies 10 MHz–1 GHz. It was established that a variation in the fraction of sp 2 bonds in carbynes induces transition from one-to two-and then to three-dimensional conduction. In the one-dimensional hopping conduction regime, the resistivity of carbynes depends on temperature as ρ=ρ0exp[(T 0/T)1/2], whereas Coulomb correlations are insignificant. The Hunt model of one-dimensional A.C. conductivity is experimentally confirmed. 相似文献

The quasi-isentropic compressibilities of deuterium and helium plasmas are measured in the pressure range 1500–5000 GPa at densities up to 8 g/cm3 using spherical experimental devices and an X-ray complex consisting of three betatrons and a multichannel optoelectronic system for taking X-ray images. The experimental results demonstrate the possibilities of high-energy-density experimental physics to reproduce the extreme states of substance typical of the Universe under laboratory conditions using the energy of traditional condensed explosives. 相似文献

It has been shown that, in polycrystalline thin PZT films with the Zr/Ti = 0.535/0.465 ratio of ions in octahedral positions of the perovskite structure, the permittivity and the pyroelectric and piezoelectric responses increase with increasing linear sizes of growth blocks to reach anomalously large values. It has been assumed that the observed effects originate from a combination of two factors, namely, the possible presence of the monoclinic phase and a well-developed domain structure in the films. 相似文献

The photocatalytic activity of thin ZnO films in the photocatalytic oxidation of the pharmaceuticals, paracetamol and chloramphenicol (Levomycetin) is reported. The films annealed at 500°C exhibit the highest activity. They have a wurtzite-like structure and consist of conducting branches, which are the spinodal decomposition products. 相似文献
