NONCOLLINEAR MAGNETIC ORDER IN THE DOUBLE PEROVSKITES: DOUBLE EXCHANGE ON A GEOMETRICALLY FRUSTRATED LATTICE
(2013)
Double perovskites (DPs) of the form A2BB′ O6 usually involve a transition metal ion, B, with a large magnetic moment, and a nonmagnetic ion B′. While many DPs are ferromagnetic, studies on the underlying model reveal the ...
Highly conductive, transparent and flexible networks of quasi 1-Dimensional metallic nanostructures
(Trinity College (Dublin, Ireland). School of Physics, 2011)
Direct current conductivity and morphological characterization has been
performed on a wide range of films made from bundled single wall carbon nanotubes,
produced by a selection of commercial suppliers. The conductivity ...
Development of stiff, strong, yet tough composites by the addition of solvent exfoliated graphene to polyurethane
(2010)
We have prepared graphene dispersions, stabilised by polyurethane in tetrahydrofuran and dimethylformamide. These dispersions can be drop-cast to produce free-standing composite films. The graphene mass fraction is determined ...
Rare-earth-free noncollinear metallic ferrimagnets Mn4-xZxN with compensation at room temperature
(2022)
Compensated ferrimagnets show no net magnetization like antiferromagnets, but their transport and magneto-optic properties resemble those of ferromagnets, thereby creating opportunities for applications in high-frequency ...
The relationship between network morphology and conductivity in nanotube films
(2008)
We have characterized both the direct current conductivity and morphology of a wide range of films made from bundled nanotubes, produced by a selection of commercial suppliers. The conductivity increases with increasing ...
Effects induced by single and multiple dopants on the transport properties in zigzag-edged graphene nanoribbons
(2009)
The effects of boron and nitrogen doping on the transport properties of zigzag-edged graphene nanoribbons
ZGNRs
with antiferromagnetically coupled edge states are investigated by first-principles electronic structure
combined ...
Nanojets and directional emission from symmetric photonic molecules
(2007)
Symmetric directional emission of light from multisphere
photonic molecules is experimentally shown in this work. The photonic
molecules are illuminated in the vertical direction with a defocused laser
beam. The emission ...
Effect of percolation on the capacitance of supercapacitor electrodes prepared from composites of manganese dioxide nanoplatelets and carbon nanotubes
(2014)
Here we demonstrate significant improvements in the performance of supercapacitor electrodes based on 2D MnO2 nano-platelets by the addition of carbon nanotubes. Electrodes based on MnO2 nano-platelets do not display high ...
Raman scattering and Anti-Stokes emission from a single spherical microcavity with a CdTe quantum dot monolayer
(American Institute of Physics, 2003)
We have studied the Raman and luminescence spectra of a microcavity?quantum dot system
consisting of a melamine formaldehyde latex microsphere coated by CdTe colloidal quantum dots.
The cavity-induced enhancement of the ...
