Title: Self-ordering of Mg and O isoelectronic impurities in ZnSe

Abstract

Self-ordering of isoelectronic magnesium and oxygen impurities in ZnSe is described. The formation of 1O4 Mg tetrahedral cells in ZnSe-enriched Mg{sub x}Zn{sub 1-x}O{sub y}Se{sub 1-y} alloy (x {>=} 4y) in the ultradilute limit (1 x 10{sup -8} {<=} y {<=} 1 x 10{sup -3}) of oxygen concentrations is predicted. Under certain conditions that are established for the temperatures of growth (300 deg. C) and annealing (500 deg. C), all of the oxygen impurity atoms should be surrounded by Mg atoms only. The origin of this phenomenon is the thermodynamic preference for Mg-O and Zn-Se bond formation compared to Mg-S and Zn-O bonds and a decrease in the elastic-stress energy after self-ordering of the alloy.

  • Self-assembling of 1O4Mg identical tetrahedral clusters resulting in the nanoscale order in ZnSe:(Mg, O) is presented. Co-doping transforms ZnSe into Mg{sub x}Zn{sub 1−x}O{sub y}Se{sub 1−y} alloy of MgO, MgSe, ZnO and ZnSe. The decrease of a sum of the enthalpies of the constituent compounds and diminution of the strain energy are the causes of this phenomenon. The self-assembling conditions are obtained from the free energy minimum when magnesium and oxygen are in the dilute and ultra dilute limits, correspondingly. The occurrence of 1O4Mg clusters and completion of self-assembling when all oxygen atoms are in clusters are results of the continuousmore » phase transitions. The self-assembling occurrence temperature does not depend on the oxygen content and it is a function of magnesium concentration. Mg{sub x}Zn{sub 1−x}O{sub y}Se{sub 1−y} with all oxygen atoms in clusters can be obtained in temperature ranges from T = 206 °C (x = 0.001, y = 1×10{sup −4}) to T = 456 °C (x = 0.01, y = 1×10{sup −4}) and from T = 237 °C (x = 0.001, y = 1×10{sup −6}) to T = 462 °C (x = 0.01, y = 1×10{sup −6})« less
  • Compositional ordering was found to occur in the ferroelectric (1 - x)Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-antiferroelectric x Pb(Mg/sub 1/2/W/sub 1/2/)O/sub 3/ solid solution system. X-ray diffraction and neutron profile fitting structure refinement were used to refine one such composition with x = 0.9. The paraelectric structure of compositions with x < 0.2 is that of the disordered perovskite (space group Pm3m), whereas for 0.2 less than or equal to x < 1.0 the structure is that of ordered perovskite (space group Fm3m). The oxygen octahedra in the ordered state are regular but no longer equivalent.
  • The oxygen vacancies distribution in the rigid lattice and the thermally activated motion of oxygen atoms are studied in La{sub 1-x}Sr{sub x}Ga{sub 1-x}Mg{sub x}O{sub 3-x} (x=0.00; 0.05; 0.10; 0.15 and 0.20) compounds. For that {sup 71}Ga, {sup 25}Mg and {sup 17}O NMR was performed from 100 K up to 670 K, and ion conductivity measurements were carried out up to 1273 K. The comparison of the electric field gradients at the Ga- and Mg-sites evidences that oxygen vacancies appear exclusively near gallium cations as a species trapped below room temperature in local clusters, GaO{sub 5/2}-{open_square}-GaO{sub 5/2}. These clusters decay atmore » higher temperature into mobile constituents of the structural octahedra Ga(O{sub 5/6{open_square}1/6}){sub 6/2}. At the same time, the nearest octahedral oxygen environment of magnesium cations persists at different doping levels. The case of two adjacent vacant anion sites is found highly unlikely within the studied doping range. The thermally activated oxygen motion starts to develop above room temperature as is observed from both the motional narrowing of {sup 17}O NMR spectra and the {sup 17}O nuclear spin-lattice relaxation rate. The obtained results show that two types of motion exist, a slow motion and a fast one. The former is a long-range diffusion whereas the latter is a local back and forth oxygen jumps between two adjacent anion sites. These sites are strongly differentiated by the probability of the vacancy formation, like the vacant apical site and the occupied equatorial site in the orthorhombic compositions x <0.15. -- Graphical abstract: Up to 700 K the vacant oxygen sites are near Ga but not near Mg.

  • CaO, MgO, and Y{sub 2}O{sub 3} doped zirconia samples were nitrided at temperature between 1400 and 2000{degrees} in a graphite heated resistance furnace in a nitrogen atmosphere. Depending on the content of nitrogen and aliovalent oxides, different types of ordered ({beta} type) and disordered (tetragonal, cubic) phases were observed. Nitridation of pure ZrO{sub 2} results in the formation of the {beta}{double_prime} phase. With increasing content of the aliovalent oxides, other {beta} type phases ({beta}{prime}, {beta}) are detectable. The stability fields of the individual {beta} type phases are determined by the ratio of V{sub N}/V{sub total} and by the kind ofmore » dopant oxide. In the system Y-Zr-O-N, the transition tetragonal-cubic was observed for higher Y{sub 2}O{sub 3} concentrations. In this case, the {open_quotes}effective{close_quotes} total concentration of vacancies is the dominant factor which controls the transition.« less
  • The temperature dependence of oxygen ordering in YBa{sub 2}(Cu{sub 1{minus}{ital x}M{ital x}}){sub 3}O{sub 7{minus}{ital y}} ({ital M}=Al,Co,Fe) is studied theoretically. A generalized mean-field model including short-range atomic correlations is used to investigate the effect of substitutional impurities on the ordering of oxygen atoms in the Cu(1) basal plane. The calculated phase diagram suggests that the macroscopically tetragonal phase observed for {ital x}{gt}0.025 and {ital y}{congruent}0 transforms at temperatures {ital T}{lt}800 K into an orthorhombic phase if the oxygen content in YBa{sub 2}(Cu{sub 1{minus}{ital x}M{ital x}}){sub 3}O{sub 7{minus}{ital y}} is reduced.
