Self-assembled broadband plasmonic nanoparticle arrays for sensing applications
(2012)
Highly ordered noble metal nanoparticle (NP) arrays are produced using a glancing angle deposition on stepped substrates. The versatility of the technique is demonstrated by depositing different metals, resulting in shifts ...
Interfacial transport properties between a strongly correlated transition metal oxide and a metal: Contact resistance in Fe3O4/M (M=Cu, Au, Pt) nanostructures
(2010)
Multiterminal measurements have typically been employed to examine electronic properties of strongly correlated electronic materials such as transition metal oxides without the influence of contact effects. In contrast, ...
Growth and ordering of Ni(II) diphenylporphyrin monolayers on Ag(111) and Ag/Si(111) studied by STM and LEED
(2012)
The room temperature self-assembly and ordering of (5,15-diphenylporphyrinato)nickel(II) (NiDPP) on the Ag(111) and Ag/Si(111)-(?3 ? ?3)R30? surfaces have been investigated using scanning tunnelling microscopy and low-energy ...
Self-assembled Fe nanodots on Ge (001)
(2006)
The initial nucleation of Fe onto the (2x1) reconstructed Ge(001) surface is studied. Uniformly sized two-dimensional Fe dots are shown to nucleate. They have an apparent corrugation height similar to 1.1 A and lateral ...
Probing the out-of-plane optical response of plasmonic nanostructures using spectroscopic ellipsometry
(2011)
A simplified approach to investigate the out-of-plane response of plasmonic nanostructures using spectroscopic ellipsometry (SE) is presented. One-dimensional self-assembled arrays of Ag nanoparticles (NP?s) were grown on ...
X-ray spectroscopic studies of the electronic structure of chromium-based p-type transparent conducting oxides
(2016)
The valence band structure of p-type transparent oxides—crystalline MgxCr2−xO3 and nanocrystalline CuxCrOy—is analyzed as a function of incoming photon energy. The valence band of both p-type transparent conducting oxides ...
Large magnetorefractive effect in magnetite
(2010)
We carried out a magneto-optical spectroscopic study of magnetite (Fe3O4) thin films and single crystals at optical wavelengths. We observed a relevant quadratic magneto-optic contribution that can be notably larger than ...
Magnetization States of All-Oxide Spin Valves Controlled by Charge-orbital Ordering of Coupled Ferromagnets
(2013)
Charge-orbital ordering is commonly present in complex transition metal oxides and offers interesting opportunities for novel electronic devices. In this work, we demonstrate for the first time that the magnetization states ...
Influence of miscut on the anisotropic magnetoresistance of magnetite
(American Physical Society, 2009)
We present the comparative measurements of the angular dependence of the anisotropic magnetoresistance (AMR) of magnetite (Fe3O4) films on MgO(001) nonvicinal and vicinal substrates (2.86? miscut along the 100 direction). ...
Magnetization Reversal Behaviour of Planar Nanowire Arrays of Fe
(2013)
Systematic investigations of magnetization behavior performed on planar arrays of 30 nm wide Fe-nanowires (NW) fabricated on oxidized step-bunched Si (111) templates reveal that the NW arrays exhibits an uniaxial anisotropy ...
