  • TEM imaging of Ag-Au nanoalloys

    Dane Badawcze
    open access

    The nanostructures of AuAg nanoalloys were prepared by sequential sputtering of metal thin layers (Au/Ag or Ag/Au) followed by annealing under 550 Celsius degree in an argon atmosphere. The basic single layer thickness was usually ca. 3 nm. For investigations two samples wih 50% Au and 50% Ag were selected and samples 1/3 Ag - 2/3 Au and 2/3 Ag - 1/3...

    open access

    The obtained data was acquired by the interferometric fiber-optic sensor of distance. The setup was constructed of a broadband light source working at the central wavelength of 1310 nm, an optical spectrum analyzer, and a fiber-optic 2x1 coupler (with the power split 50:50). All elements were connected by standard single-mode optical fibers. The measurement...

  • TEM and EDX study of the Al2O3 ultra thin films

    Dane Badawcze
    open access

    The ultra-thin layers of Al2O3 were deposited on a silicon substrates. The method of atomic layer deposition (Beneq TFS 200 ALD system) was chosen as the proper method of dielectric layer deposition. This method provides precise thickness control down to a single atomic layer. The precursors used were trimethylaluminum (Sigma-Aldrich) and purified water....

    We show anisotropy in the superconductivity for boron-doped diamond thin films prepared with Microwave Plasma Assisted Chemical Vapor Deposition using deuterium-rich plasma. This anomalous phase transition is linked with the emergence of boson quantum entanglement states behaving as a bosonic insulating state. Here, we show that the superconducting...
