Irreversibility line, Hall effect, and longitudinal resistivity measurements on cobalt-doped yttrium barium(2) copper(3) oxygen(7-delta)
… x})\sb3$O$\sb{7-\delta}.$ By high-pressure oxygen annealing, we produced single crystals having transition temperatures, T$\sb{\rm c}$, comparable with those of polycrystalline samples of the same cobalt concentration.

Probing nano-scale atomic and electronic structures of iron-based superconductors
… on the electronic structure by isovalent doping. Oxygen annealing effect is studied next in single crystals of Fe1.08Te0.55Se0.45. The as-grown sample with the tetragonal PbO-type structure is non-superconducting owing to the excess Fe beyond the stoichiometric content of 1. Superconductivity is …

Investigations On Rf Sputter Deposited Sicn Thin Films For Mems Applications
… Further, the films were annealed in dry oxygen ambient in the temperature range of 400 – 900°C and characterized using XPS to investigate the chemical composition and oxidation kinetics at each annealing temperature. The surface roughness of these films was studied as a function of …

Integrated Growth and Process Technology for Atomically Thin Single Crystal Films
… can supply a Cu catalyst with a low level oxygen that was long undetected due to the limitations of common surface measurements. This oxygen is not only shown to increase the defect density of the graphene films, but also to significantly increase the frequency and size of unwanted adlayers …
