The Onset of Phase Separation in the Double Perovskite Oxide LaMnNiO
Steven R. Spurgeon, Peter V. Sushko, Arun Devaraj +3
Identification of kinetic and thermodynamic factors that control crystal nucleation and growth represents a central challenge in materials synthesis. Here we report that apparently…
Band-gap engineering at a semiconductor - crystalline oxide interface
J. Moghadam, K. Ahmadi-Majlan, X. Shen +6
The epitaxial growth of crystalline oxides on semiconductors provides a pathway to introduce new functionalities to semiconductor devices. Key to electrically coupling crystalline…
Self-corrected sensors based on atomic absorption spectroscopy for atom flux measurements in molecular beam epitaxy
Y. Du, T. C. Droubay, A. V. Liyu +2
A high sensitivity atom flux sensor based on atomic absorption spectroscopy has been designed and implemented to control electron beam evaporators and effusion cells in a molecular…
Ion irradiation of Fe-Fe oxide core-shell nanocluster films: Effect of interface on stability of magnetic properties
John S. McCloy, Weilin Jiang, Timothy C. Droubay +7
A cluster deposition method was used to produce films of loosely aggregated nanoclusters (NC) of Fe core-Fe3O4 shell or fully oxidized Fe3O4. Films of these NC on Si(100) or MgO(10…
Unintentional F doping of the surface of SrTiO3(001) etched in HF acid -- structure and electronic properties
Scott A. Chambers, Timothy C. Droubay, Cigdem Capan +1
We show that the HF acid etch commonly used to prepare SrTiO3(001) for heteroepitaxial growth of complex oxides results in a non-negligible level of F doping within the terminal su…
LaCrO3 heteroepitaxy on SrTiO3(001) by molecular beam epitaxy
L. Qiao, T. C. Droubay, M. E. Bowden +3
Stoichiometric, epitaxial LaCrO3 films have been grown on TiO2-terminated SrTiO3(001) substrates by molecular beam epitaxy using O2 as the oxidant. Film growth occurred in a layer-…
