Structural state of metastable cubic compounds Ni1 − x Zn x O (0.6 ≤ x ≤ 0.99)

ZnO under Pressure: From Nanoparticles to Single Crystals

“…Some structural [51][52][53][54][55], optical [56][57][58][59][60][61][62] and magnetic [40,52] properties of recovered cubic ZnO-based solid solutions were studied under ambient pressure. The fine crystalline structure of cubic Ni 1−x Zn x O [51,52] and Mg 1−x Zn x O [53] solid solutions has been examined in a wide concertation range by X-ray powder diffraction.…”

It has been found that the diffraction patterns of these compounds contain a system of superlattice diffuse lines, the number and intensity of which depend on the composition [51,52].…”

It has been found that the diffraction patterns of these compounds contain a system of superlattice diffuse lines, the number and intensity of which depend on the composition [51,52]. It was found that an integrated intensity ratio between the 111 and 002 reflections correlated with zinc fraction in polycrystalline Mg 1−x Zn x O solid solutions [53].…”

Phase stability and thermal expansion of ZnO solid solutions with 3d transition metal oxides synthesized at high pressure

“…Examples of materials interesting from the point of view of their semiconducting properties are ZnO solid solutions with magnesium oxide [2,3] and nickel oxide [4,5]. The research is developing in two directions: epitaxial stabilization of rs-ZnO in thin films on oriented substrates [2][3][4][5] and high-pressure phase transition of wurtzite ZnO into cubic one [6][7][8][9][10][11][12][13][14][15][16].…”

“…Crystallographic features of the structure [14][15][16][21][22][23][24], functional properties [4,5,8,15,22] and thermal expansion [21,25,26] of simple and complex metastable oxide systems remain a subject of particular attention due to future prospects for their practical application. At the same time, systematic studies of thermal stability of metastable solid solutions depending on the nature of the substituent cations have not been performed, and such data are absent in the literature.…”
