Answer 2

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 electron spectroscopy. Oxygen forms two structures with long-range order on this surface: a p(2×2) phase in which the full coverage is 1/4 and a (sqrt[3]×sqrt[3])R 30∘ structure with full coverage of 1/3. These phases are separated in coverage by a poorly ordered transition phase. The p(2×2) phase at full coverage (θ=0.25) exhibits a continuous order-disorder transition at Tc=440 K. A tricritical point, corresponding to the intersection of boundaries of a disordered "gas" phase, a single-phase p(2×2) region, and a mixed-phase region of p(2×2) islands surrounded by gas, was found at θ=0.21, Tt=300 K. The (sqrt[3]×sqrt[3])R 30∘ phase was observed at θ>0.29 and T<300 K. This phase was characterized by a first-order discontinuous phase boundary. The work function increased smoothly with oxygen coverage
