The lattice parameter changed linearly with the ionic radius of the M atom and the amount of oxygen defect. A simple formula is proposed for the lattice parameter expectation. The thermal conductivity decreased according to the differences in atomic mass and ionic radius. For trivalent ion-added ...
Lattice parameter refers to the constant distance between unit cells in a crystal structure, as indicated by the lattice parameters provided in the table for various plumbides in the periodic table sequence.

Add the atomic radii to obtain the combined radius: R1 + R2. For example, if determining the lattice parameter of GaAs, add the atomic radii of Ga and As. The combined radius is 0.246 nm = 0.126 nm + 0.120 nm = R1 + R2. Step 3 Calculate the zinc-blende lattice parameter (a) us...
Once the DFT data set was prepared, the SNAP coefficients \(\{{\beta }_{0},\,\beta \}\) and hyperparameters (namely, atomic weights, \(\{w\}\), and radius cutoff, \(\{{R}_{{cut}}\}\)) were trained via the following two-step iterative approach as illustrated in Supplementary...
(Table1and Supplementary Note3). This enlarged behavior of the phonon Grüneisen parameter in Sr2ZnSb2is also captured by the average Grüneisen parameters,\(\bar{\gamma }=d{{{\mathrm{ln}}}\left\langle E\right\rangle /d{{{\mathrm{ln}}}V\), where\(\left\langle E\right\rangle=\int ...

whereJX(j)Y(l)is the pair-wise interatomic potential between elementXandYat sitesjandl, respectively,clis the occupation parameter of sitel, andJ0is the concentration-dependent part. Summing up the energy over all theNatomic sites yields the total energy of the lattice: ...
where D0 is the mineral/melt “strain-compensated” partition coefficient for an element with the ionic radius (r0) corresponding to the size of a specific site, and rj is the ionic radius of the element j. The parameter E is an elastic response of the lattice to strain caused by hosting...

Because the atomic radius of Ce was larger,adding trace amounts of the Ce to the alloy causes distortion of lattice parameter. 由于Ce原子半径大,Ce的添加可使合金点阵参数发生畸变,合金强度、硬度得到进一步提高,并有助于提高触点材料的耐磨性。 更多例句>> 3...
