(2000-10-01)Hydrogenated amorphous silicon films co-doped with oxygen (O), boron (B) and phosphorus (P) were fabricated using PECVD technique. The erbium (Er) implanted samples were annealed in a N2 ambient by rapid thermal annealing. ...
-
(2000-01-01)We report the results of first-principles calculations on the electronic structure in ferromagnetic and non-magnetic hexagonal MnV (V = As, Sb, Bi). The calculations are based on the local-spin-density approximation (LSDA) ...
-
(2000-01-01)The abundant generalized dromion structures for the (2+1)-dimensional KdV equation are obtained using the homogeneous balance method. We give not only the general curve soliton which is finite on a curved line and localized ...
-
(2000-11-01)A modified Bragg law for straightforward determining the film thickness by low-angle X-ray reflection was derived based on the geometrical optical theory. We showed that this modified Bragg law and its inference formulae ...
-
(2000-08-01)We develop a Frenkel-Kontorova model to analyze the microscopic origins of vacancy-line interactions in a pseudomorphic adsorbate system. The atomic positions in the ground states are obtained by use of the gradient method. ...
-
(2000-02-01)Chaotic characteristics in the iteration of logistic map(one-dimensional discrete dynamic system) are simulated and analyzed. The circuit implementation of a kind of chaotic amplifier model is based on the chaotic ...
-
(2000-01-01)From transition-rate-equations and transmission-equations the formulas of threshold power are deduced for an end-pumped laser, in which the probability of cross-relaxation cannot be ignored and the nonradiative ...
-
(2000-12-01)The absorption spectrum of HD16 O was recorded at a resolution of 0.02 cm-1 with a Bruker IFS 120HR Fourier Transform Spectrometer in the region of 9600-10200 cm-1. As far as we know it is the first time to record and ...
-
(2000-11-01)A new technique to uniformly align liquid crystal molecules is presented. The technique is based on producing an anisotropic surface on the glass substrate coated with photo-polymers by photo-polymerization of linear ...
-
(2000-04-01)Seven absorption group-bands (1D2, 1G4, 3F2, 3F3, 3H4, 3H5, 3F4) of Tm3+ in YVO4 single crystals have been observed in the orientation absorption spectra recorded in the spectral range from 200 to 4000 nm at 300K. The ...

(2000-12-01)By appropriately choosing additional dimensions of space-time, the mass spectrum of mesons was obtained, and the calculated results agree with the experimental data.
-
(2000-11-01)An approximate model is proposed to study the stabilization problem of hydrogen atoms under monochromatic intense laser field. The stabilization regime for system parameters such as laser field strength, laser field frequency ...
-
(2000-10-01)This paper presents the results of research on microwave breakdown in air, it includes the experimental study and the theoretical analysis. The experimental study has been done in a waveguide with a frequency of 9.37GHz, ...
-
(2000-10-01)Amorphous silicon (a-Si) nanowires have been prepared on SiO2/Si substrates by AuPd nanoparticles / silane reaction method. Field-emission scanning electron microscopy and transmission electron microscopy were used to ...
-
(2000-04-01)A method for analyzing the elasticity problem of cubic quasicrystal is developed. The axisymmetric elasticity problem of cubic quasicrystal is reduced to a single higher-order partial differential equation by introducing ...
-
(2000-01-01)The transition energies between n = 3 and n = 2 of the Ne-like ion Ge22+, Se24+, Zr30+, Rh35+, Ag37+, Sb41+, Xe44+, La47+, Nd50+ and Eu53+ are calculated by adding polarization in the core. The systematic errors in ...
-
(2000-03-01)The interaction between soliton and sinusoidal wave in two weakly coupled long Josephson junctions is studied. Theoretical analysis reveals that the soliton may be embedded in Melnikov chaotic attractors and the Fiske-step-modes ...
-
(2000-08-01)By using the bosonization and renormalization group methods, we have studied the low energy physical properties in the one-dimensional dimerized Hubbard model. The formation of charge and spin gaps is investigated both for ...
-
(2000-11-01)We report the construction of an optical tweezers system and the results of the trapping and the moving of living algal cells. Experimental study on trapping polystyrene spheres demonstrates the effects of the system ...
-
(2000-07-01)It is shown that for the ideal internal kink mode of tokamak plasma, there exists a critical magnetic shear s0c for its excitation when the finite ion Larmor radius effect is considered in the mode singular layer. This can ...
