Spinodal phase segregation

Unlike the heterostructures whose periodic structure must be accurately controlled, the formation of nanocomposite structure is self-organized based upon thermodynamically driven spinodal phase segregation [118-121]. For the CVD... 

These considerations lead us to propose the tentative phase diagram of fig. 28. The orthorhombic-rhombohedral transition has been tracked by Wold and Arnott (1959). The two-phase region 0.05 < 5 < 0.10 observed by room-temperature X-ray diffraction has been shown from the spin-glass behavior below 7 to extend over a wider compositional range below 200 K, which indicates that a spinodal phase segregation separates the O -orthorhombic (c/a < x/2) from an O -orthorhombic (c/a J2) or R-rhombohedral phase. With neutron powder diffraction, Huang et al. (1997) have shown the two-phase region at 300 Kin the inter-...
