Domain-wall-to-domain interconversion in a polar conducting oxide
Martin F. Sarott, Majid Ahmadi, Johanna van Gent González +13
Domain walls in ferroic crystals are topological defects with a symmetry distinct from the domain interior, allowing them to display functionalities that are otherwise forbidden in…
Surface-Sensitive Raman Scattering by Transferable Nanoporous Plasmonic Membranes
Roman M. Wyss, Günter Kewes, Martin Frimmer +11
Raman spectroscopy is a powerful technique to characterize materials. It probes non-destructively chemical composition, crystallinity, defects, strain and coupling phenomena. Howev…
Role of the ferroelastic strain in the optical absorption of BiVO4
Christina Hill, Mads C. Weber, Jannis Lehmann +4
Bismuth vanadate (BiVO4) has recently been under focus for its potential use in photocatalysis thanks to its well-suited absorption edge in the visible light range. Here, we charac…
Crossover in the pressure evolution of elementary distortions in RFeO3 perovskites and its impact on their phase transition
R. Vilarinho, P. Bouvier, M. Guennou +9
This work reports on the pressure dependence of the octahedra tilts and mean Fe-O bond lengths in RFeO3 (R=Nd, Sm, Eu, Gd, Tb and Dy), determined through synchrotron X-ray diffract…
Raman spectroscopy of rare-earth orthoferrites RFeO3 (R = La, Sm, Eu, Gd, Tb, Dy)
Mads Christof Weber, Mael Guennou, Hong Jian Zhao +5
We report a Raman scattering study of six rare earth orthoferrites RFeO3, with R = La, Sm, Eu, Gd, Tb, Dy. The use of extensive polarized Raman scattering of SmFeO3 and first-princ…
Multiple strain-induced phase transitions in LaNiO3 thin films
M. C. Weber, M. Guennou, N. Dix +9
Strain effects on epitaxial thin films of LaNiO3 grown on different single crystalline substrates are studied by Raman scattering and first-principles simulation. New Raman modes,…
Temperature evolution of the band-gap in BiFeO3 traced by resonant Raman scattering
Mads Christof Weber, Mael Guennou, Constance Toulouse +4
Knowledge of the electronic band structure of multiferroic oxides, crucial for the understanding and tuning of photo-induced effects, remains very limited even in the model and tho…
Probing individual layers in functional oxide multilayers by wavelength-dependent Raman scattering
J. Kreisel, M. C. Weber, N. Dix +3
Integration of functional oxides on silicon requires the use of complex heterostructures involving oxides of which the structure and properties strongly depend on the strain state…
Phonon Raman scattering of RCrO3 perovskites (R = Y, La, Pr, Sm, Gd, Dy, Ho, Yb, Lu)
M. Weber, J. Kreisel, P. A. Thomas +3
We report a systematic investigation of orthorhombic perovskite-type RCrO3 powder samples by Raman scattering for nine different rare earth R3+ cations (R = Y, La, Pr, Sm, Gd, Dy,…
