Atomic Layer Deposition of Ruthenium Films on Strontium Titanate

Journal of Nanoscience and Nanotechnology, 2011
Atomic layer deposition of ruthenium on SrTiO3 layers was investigated using (C2H5C5H4). (NC4H4)Ru and air as precursors. For comparison, the growth was studied also on ZrO2 films and SiO2/Si surfaces. Deposition temperature was 325 degrees C. Using rather short but intense air pulses, smooth and uniform Ru films were deposited on SrTiO3.

Spectroscopy with cold and ultracold strontium atoms

2003 European Quantum Electronics Conference. EQEC 2003 (IEEE Cat No.03TH8665), 2003
Photoassociation spectroscopy is used to probe the ro-vibrational spectrum of the strontium dimer at the at the /sup 1/S/sub 0/ + /sup 3/P/sub 1/ - asymptote by measuring the trap loss depending on the frequency of a photoassociation laser red-detuned to the 1S/sub 0/-3P/sub 1/ transition.

Excitation of strontium atom in electron–atom collisions

Journal of Applied Spectroscopy, 2010
The excitation of 3D levels of strontium atom by slow monoenergetic electrons has been studied experimentally. Thirty six excitation cross-sections were measured at 30-eV electron energy. Optical excitation functions for most of the transitions were recorded in the 0–200-eV electron-energy range.

Atomic Displacements in Perovskite Strontium Titanate

Annalen der Physik, 1970
AbstractThe relative atomic displacements of the sublattices of perovskite strontium titanate associated with optical frequency mode are calculated using all possible interionic couplings. The couplings are estimated from the observed optical frequencies of SrTiO3. The results of the calculation are plotted as a function of a parameter Φ(∼T – Tc).

Dispersion and polarization interactions of the strontium atom

Molecular Physics, 2010
Dispersion coefficients involving the 5s 2 1 S e and 5s5p 1,3P o states of strontium are determined from a large basis configuration interaction calculation. Dispersion coefficients are presented for the strontium dimer and also for strontium interactions with hydrogen and the rare gases.

Electrothermal atomization of calcium and strontium in a molybdenum micro-tube

Talanta, 1981
The excitation and ionization of calcium and strontium in a molybdenum micro-tube atomizer and their use in atomic-absorption spectrometry are described. Increasing hydrogen flow led to complex calcium atomization profiles for absorption measurements, but decreasing hydrogen flow resulted in higher atomic emission.

Asymmetric two-electron excitations in atomic strontium and barium

Physical Review A, 1994
We present a general nonperturbative calculation of the photoionization cross section for highly asymmetrical two-electron systems. The calculations were performed using the eigenchannel [ital R]-matrix procedure together with multichannel quantum-defect theory, including the effects of long-range multipole interactions. The isolated-core approximation

Quantum computing with neutral strontium atoms

2023
In our project we aim to build a quantum co-processor as part of a hybrid quantum computer. This will be experimentally realized by trapping strontium-88 atoms in a 2D array of optical tweezers, generated by a spatial light modulator. As qubit states we plan to use the ground 1S0, and clock state 3P0 of the Sr atom.

Activation of dimethyl ether with barium and strontium atoms

Journal of Organometallic Chemistry, 1980
Abstract Organometallic compounds are produced when barium and strontium atoms are cocondensed with dimethyl ether at −196°C; hydrolysis of the cocondensation products from both reactions yields mainly C1—C8 alkanes, alkenes, and alkynes.

Hybrid Quantum Computing with Strontium Atoms

2021
A hybrid quantum computer tailored for quantum chemistry applications will be constructed. The quantum co-processor will consist of two-dimensional arrays of ultracold Strontium-88 atoms in optical tweezers with multiple qubit operations realized using Rydberg states.
