The ideal stoichiometry for the B2 ordered phase is Fe–Ga (x = 50). However, the B2 phase is stable over a wide range of non-stoichiometric compositions at high temperatures, even at Ga compositions as low as x ≈ 22. For Ga-deficient compositions with x < 50, the B2 structure can...
A long-range ordered (LRO) structure with 2a x 2a periodicity is formed in 1T-TiSe2 flakes by electron beam irradiation. Transmission electron microscopy shows that the LRO structure is not only formed in the area irradiated by the electron beam, but also in the adjacent unirradiated area ...
It is well known that structural vacancies of carbon in nonstoichiometric titanium carbide form a long-range order structure in the carbon sublattice. For the superlattice structure of titanium carbide, two structures have been proposed; a cubic space group Fd3m and a rhombohedral space group R3m...
The ordered structure exhibits superior elevated-temperature properties because of the long-range ordered superlattice, which reduces dislocation mobility and diffusion processes at elevated temperatures. en.wikipedia.org To complete the course, cadets were required to spend 100 hours navigating during both...
Crystal is a long-range ordered structure formed by the periodic arrangement of atoms,ions,or molecules in confined space.The ordered arrangement of building blocks in crystals would give rise to unique optical,mechanical,thermal conductivity and electrical properties,driving their widespread application ...
lamellar structure in long-range ordered 未'-TiN_0.5 phase was analyzed by transmission elec- tron microscopy (TEM), and the crystallographic properties of the lamellar structure were discussed in terms of the crystal symmetry changes before and after transformation. It was shown that the lamellar ...
The ordered structure exhibits superior elevated-temperature properties because of the long-range ordered superlattice, which reduces dislocation mobility and diffusion processes at elevated temperatures. en.wikipedia.org The spectral density function of long-range dependence follows a power law near the ori...
Exfoliation has been used to obtain 2D materials with attractive properties, like graphene. The layered structure of silk and its structural transition to
Regardless of the insulating nature of the bulk MgO, the bandgap of which is measured to be 7.4鈥塭V, the MgO 1D ordered structure is a wide-bandgap semiconductor with a bandgap of 3.2鈥塭V owing to this special atomic arrangement. The discovery of 1D ordered structures suggests that the ...
