A pseudopotential depending on an effective core radius is proposed to study the binding energy, equation of state, ion-ion interaction, phonon dispersion curves (q-space and r-space analysis), mode Gr眉neisen parameters and dynamical elastic constants of some fcc f-shell metals La, Yb, Ce ...
Using the equation above, the primitive translation vectors of the reciprocal lattice of the BCC lattice are b1=2πa(0,1,1)b2=2πa(1,0,1)b3=2πa(1,1,0) The volume of the parallelepiped defined by Ωrl=2(2π/a)3 Notice that the reciprocal lattice of the FCC direct space la...
A variety of models, which have been proposed in the past, were considered, and the calculated values of y were compared with the observed values. The best agreement was achieved with values computed with Friedel's equation, (auth)关键词: metals, ceramics, and other materials cerium alloys ...
The equation has the following initial and boundary conditions, N (0, z) ∝ exp− z α , (2) Scientific Reports | 6:19302 | DOI: 10.1038/srep19302 3 www.nature.com/scientificreports/ Figure 3. (a,b) Transient absorption spectra of the 1.5 eV ...
Configurations were found using a digital computer by choosing a starting configuration roughly approximating the situation under consideration and successively adjusting the value of each variable occurring in the energy equation so that the magnitude of the generalized force associated with it was zero ...
There arise substantial regions of energy (energy gaps) in which wavelike solutions of the Schroedinger equation do not exist [Kozima 1998d]. The low-energy portions of the band structure are qualitatively similar to that for entirely free electrons. The energy spectrum has the energy gaps at ...
The reciprocal lattice can be specified in terms of a set of reciprocal lattice vectors G that satisfy the equation (1.6)eiG•T=1 for all allowed combinations of the Miller indices h, k, l. Since each Bravais lattice is described by a different set of T, each will also have a ...
In particular we look at results for the order of the finite temperature phase transition and the quantitative determination of the transition temperature as well as the equation of state and screening lengths in the QCD plasma phase. We also discuss briefly first experimental attempts to study ...
Compute the linear densities of the following fcc directions: <1 0 1>, <0 1 0>, and <1 1 1>. For the shape shown below, determine the location of the centroid (x,y). The boundary layer profile can be approximated using a cubic equation, as shown below , ...
