Experimental verification of orbital engineering at the atomic scale: charge transfer and symmetry breaking in nickelate heterostructures
Patrick J. Phillips, Paolo Longo, Alexandru B. Georgescu +7
Epitaxial strain, layer confinement and inversion symmetry breaking have emerged as powerful new approaches to control the electronic and atomic-scale structural properties in comp…
Hysteretic electrical transport in BaTiO/BaSrTiO/Ge heterostructures
J. H. Ngai, D. P. Kumah, C. H. Ahn +1
We present electrical transport measurements of heterostructures comprised of BaTiO and BaSrTiO epitaxially grown on Ge. The Sr-alloying imparts compressive str…
Resonant phonon coupling across the La{1-x}Sr{x}MnO{3}/SrTiO{3} interface
Y. Segal, K. F. Garrity, C. A. F. Vaz +4
The transport and magnetic properties of correlated La{0.53}Sr{0.47}MnO{3} ultrathin films, grown epitaxially on SrTiO{3}, show a sharp cusp at the structural transition temperatur…
Origin of the magnetoelectric coupling effect in Pb(Zr0.2Ti0.8)O3/La0.8Sr0.2MnO3 multiferroic heterostructures
C. A. F. Vaz, J. Hoffman, Y. Segal +5
The electronic valence state of Mn in Pb(Zr0.2Ti0.8)O3/La0.8Sr0.2MnO3 multiferroic heterostructures is probed by near edge x-ray absorption spectroscopy as a function of the ferroe…
Epitaxial Growth of Multiferroic YMnO3 on GaN
A. Posadas, J. -B. Yau, J. Han +5
In this work, we report on the epitaxial growth of multiferroic YMnO3 on GaN. Both materials are hexagonal with a nominal lattice mismatch of 4%, yet x-ray diffraction reveals an u…
