Ultrathin, sputter-deposited, amorphous alloy films of ruthenium and molybdenum
G. Yetik, A. Troglia, S. Farokhipoor +5
Microscopy and diffraction measurements are presented of ultrathin binary alloy films of ruthenium and molybdenum that are obtained by standard sputter deposition. For compositions…
Patterning enhanced tetragonality in BiFeO3 thin films with effective negative pressure by helium implantation
C. Toulouse, J. Fischer, S. Farokhipoor +13
Helium implantation in epitaxial thin films is a way to control the out-of-plane deformation independently from the in-plane strain controlled by epitaxy. In particular, implantati…
Large magnetoelectric coupling in multiferroic oxide heterostructures assembled via epitaxial lift-off
David Pesquera, Ekaterina Khestanova, Massimo Ghidini +12
The strain dependent functional properties of epitaxial transition metal oxide films can be significantly modified via substrate selection. However, large lattice mismatches preclu…
Tunable resistivity exponents in the metallic phase of epitaxial nickelates
Qikai Guo, Saeedeh Farokhipoor, César Magén +2
We report a detailed analysis of the electrical resistivity exponent of thin films of NdNiO3 as a function of epitaxial strain. Strain-free thin-films show a linear dependence of t…
Resistive switching in ferroelectric BiFeO3 by 1.7 eV change of the Schottky barrier height
Saeedeh Farokhipoor, Beatriz Noheda
Using metal-ferroelectric junctions as switchable diodes was proposed several decades ago. This was shown to actually work in PbZr(1-x)TixO3 (PZT) by Blom et al. [P.W. M. Blom et a…
Local conductivity and the role of vacancies around twin walls of (001)-BiFeO3 thin films
S. Farokhipoor, B. Noheda
BiFeO3 thin films epitaxially grown on SrRuO3-buffered (001)-oriented SrTiO3 substrates show orthogonal bundles of twin domains, each of which contains parallel and periodic 71o do…
Conduction through 71o domain walls in BiFeO3 thin films
S. Farokhipoor, B. Noheda
Local conduction at domains and domains walls is investigated in BiFeO3 thin films containing mostly 71o domain walls. Measurements at room temperature reveal conduction through 71…
Tuning the atomic and domain structure of epitaxial films of multiferroic BiFeO3
C. J. M. Daumont, S. Farokhipoor, A. Ferri +4
Recent works have shown that the domain walls of room-temperature multiferroic BiFeO3 (BFO) thin films can display distinct and promising functionalities. It is thus important to u…
