The complete phase diagram of oxygen atoms chemisorbed on Ni(111) has been determined. The two-dimensional system is realized for oxygen coverages of 0.5 monolayers and temperatures 500 K. At higher coverages and temperatures oxygen is incorporated into the bulk. The structure of the oxygen overlayer was determined by low-energy electron diffraction and the coverage was monitored by Auger ...

Phase diagram for oxygen

The phase diagram of solid oxygen at terapascal pressures and several thousand Kelvin has been studied with ab initio density functional theory within the quasiharmonic approximation for the vibrational free energy. Our work extends previous theoretical studies done at zero temperature and shows that temperature has a dramatic effect on the sequence of phases. Phase diagrams of as-grown and O 2-annealed FeTe 1−x Se x determined from magnetic susceptibility measurement were obtained. For as-grown samples, the antiferromagnetic order was fully suppressed in the range region x≥0.15, and weak superconductivity appeared when x≥0.1.Beginning at x=0.5, weak superconductivity was found to evolve into bulk superconductivity.

Phase diagram for oxygen. STEM Interactives. Molecular models are the heart of Next-Generation Molecular Workbench. We've created many models that dynamically illustrate scientific concepts and allow you to interact with molecules or macroscopic phenomena like pendulums (at right) and their environment in various ways. Oxygen is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. The oxygen phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the oxygen boiling point with changes in pressure. Extended phase diagram of oxygen. The dashed lines represent the previous phase diagram reviewed in Refs. [3, 4, 23] which in turn is replotted by continuous lines in the inset.

We have studied the coverage-temperature phase diagram of chemisorbed oxygen on Ni(100) with LEED and AES. We find that the oxygen p(2 × 2) structure undergoes a nearly reversible order- disorder phase transition for coverages between 0.15 and 0.30 monolayer (T c ≈ 560 K for θ = 0.25). For these coverages, it is also found that the chemisorbed oxygen begins dissolving into the bulk nickel ... , New pressure-density-temperature measurements and new rational equations for the saturated liquid and vapor densities of oxygen, J.

A complete phase diagram of oxygen atoms adsorbed on a Pt (111) surface with oxygen coverages below half a monolayer has been computed and compared with the surface phase diagrams of related systems. Effective interaction parameters of a lattice model for the triangular lattice of the fcc sites of the Pt (111) surface were determined from first-principles computations.
