Dependence of electronic structure of SrRuO3 and the degree of correlation on cation off-stoichiometry
نویسندگان
چکیده
We have grown and studied high quality SrRuO3 films grown by MBE as well as PLD. By changing the oxygen activity during deposition we were able to make SrRuO3 samples that were stoichiometric (low oxygen activity) or with ruthenium vacancies (high oxygen activity). Samples with strontium vacancies were found impossible to produce since the ruthenium would precipitate out as RuO2. The volume of the unit cell of SrRuO3 becomes larger as more ruthenium vacancies are SLAC-PUB-13942

Some new compounds based on bis-benzimidazole moieties have been synthesized and characterized by IR and NMR spectroscopies. The ability of 3a in transition metal cation sensing such as Co2+, Ni2+, Zn2+, Mn2+, Fe2+ and Cu2+ have been investigated by Uv-vis and fluorescence spectroscopy in methanol solvent. The complexation constants and complex stoichiometry of Cu2+ have been determined. The ex...
متن کاملInvestigation of electron correlation effects in armchair silicene nanoribbons
In this study, the electronic structure of armchair silicene nanoribbons (ASiNRs) is investigated for various widths using first-principle calculations and the framework of the density functional theory. Electronic structure of ASiNRs shows a direct band gap which is decreased with increasing the nanoribbon's width, showing an oscillatory behavior. The effective Coulomb interaction between loca...

The complexation reaction between hydroxyl ammonium (HONH3+ ) cation with 18-crown-6 (18C6) ligand was studied in dimethylsulfoxide – water (DMSO-H2O), methanol – water (MeOH-H2O) and dimethylformamid – methanol (DMF-MeOH), binary solutions at different temperatures using conductometric method. The obtained results show that the stoichiometry of t...
