Crystal-field states and defect levels in candidate quantum spin ice CeHfO
Victor Porée, Elsa Lhotel, Sylvain Petit +8
We report the synthesis of powder and single-crystal samples of the cerium pyrohafnate and their characterization using neutron diffraction, thermogravimetry and X-ray absorption s…
Formation of orbital molecules on a pyrochlore lattice induced by A-O bond covalency
A. Krajewska, A. Yaresko, J. Nuss +15
The pyrochlore ruthenate InRuO displays a subtle competition between spin-orbital entanglement and molecular orbital formation. At room temperature, a spin-orbit-entang…
Pseudomagnetic fields and strain engineering: graphene on GaN nanowires
Jakub Kierdaszuk, Paweł Dąbrowski, Maciej Rogala +11
Gallium nitride nanowire and nanorod substrates with different morphology are prospective platforms allowing to control the local strain distribution in graphene films top of them,…
Highly effective gating of graphene on GaN
Jakub Kierdaszuk, Ewelina Rozbiegała, Karolina Piętak +8
By using four layered graphene/gallium nitride (GaN) Schottky diodes with an undoped GaN spacer, we demonstrate highly effective gating of graphene at low bias rendering this type…
Lattice dynamics and structural transition of the hyperhoneycomb iridate -LiIrO investigated by high-pressure Raman scattering
Sungkyun Choi, Heung-Sik Kim, Hun-Ho Kim +8
We report a polarized Raman scattering study of the lattice dynamics of -LiIrO under hydrostatic pressures up to 7.62 GPa. At ambient pressure, -LiIrO exhibit…
Surface-enhanced Raman scattering in graphene deposited on AlGaN/GaN axial heterostructure nanowires
Jakub Kierdaszuk, Mateusz Tokarczyk, Krzysztof M. Czajkowski +11
The surface-enhanced Raman scattering in graphene deposited on AlxGa1-xN/GaN axial heterostructure nanowires was investigated. The intensity of graphene Raman spectra was found not…
