  • 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....

  • Linear impedance of vanadate glass-ceramics containing BaTiO3

    Dane Badawcze

    The linear impedance of vanadate glass-ceramics containing BaTiO3 was measured. Samples of the composition of x[BaO,TiO2]–(80 − x)V2O5–20Bi2O3 where x = 5, 10 and 15 in mol% were prepared by a conventional melt quenching technique. The melting was performed in alumina crucibles at the temperature of 1273 K–1373 K. The melts were poured on a preheated...

  • Nonlinear impedance of vanadate glasses containing BaTiO3

    Dane Badawcze

    The nonlinear impedance of vanadate glasses doped with BaTiO3 was measured. Samples of the composition of x[BaO,TiO2]–(80 − x)V2O5–20Bi2O3 where x = 5, 10 and 15 in mol% were prepared by a conventional melt quenching technique. The melting was performed in alumina crucibles at the temperature of 1273 K–1373 K. The melts were poured on a preheated (573...

  • Nonlinear high temperature impedance of 35P2O5-30Fe2O3-35Nb2O5 glass

    Dane Badawcze

    The nonlinear high temperature impedance of iron- phosphate glasses doped with niobium oxide was measured.  Glass samples of the composition of 35P2O5-30Fe2O3-35Nb2O5 (in %mol) were prepared by the conventional melt quenching technique. Appropriate amounts of reagents ((NH4)2HPO4 (≥99.9%, POCH), Fe2O3 (≥99.9%, POCH) and Nb2O5 (≥99.9%, PLUKA AG) were...
