An alternative fluorine precursor for the synthesis of SnO2:F by spray pyrolysis
(2012)
An alternative, non-toxic precursor was employed for the synthesis of SnO2:F transparent conducting oxide. The performance of benzenesulfonyl fluoride (BSF) as F source for spray pyrolysis was investigated. Its decomposition ...
Magnetoresistance of Nanoscale Domain Walls Formed in Arrays of Parallel Nanowires
(2019)
We present the possibility of enhancing magnetoresistance by controlling nanoscale domain wall (DW)
width in a planar nanowire array. Results based on the micromagnetic calculations show that DW width
decreases with ...
Magnetic Properties of Exchange-Biased [Co/Pt](n) Multilayer With Perpendicular Magnetic Anisotropy
(2010)
Perpendicular exchange-biased [Co/Pt](3)/Co(t(Co))/IrMn and IrMn/Co(t(Co))/Pt/[Co/Pt](3) multilayers have been fabricated, changing the thickness (t(Co)) of the cobalt that is next to the IrMn layer. The crystal structure, ...
The Optics and Photonics of Two-Dimensional Nanomaterials
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)
In this work, by using a broadspectrum angle-resolved absorption technique, we studied enhanced absorption from multi-layered materials with near-zero dielectric permittivity in the near-infrared. These materials, known ...
From radio to X-ray: The quiescent atmosphere of the dMe Flare Star EV Lac
(2006)
We report on multi-wavelength observations spanning radio to X-ray wavelengths
of the M dwarf flare star, EV Lacertae, probing the characteristics of
the outer atmospheric plasma from the upper chromosphere to the corona. ...
Point contact Andreev reflection and tunneling spectroscopy using high-field superconductors, topological insulators and compensated ferrrimagnets
(Trinity College (Dublin, Ireland). School of Physics, 2017)
Spin electronics is a young and thriving research and technology field which relies more on the spin of the electron rather than its charge. The tunneling magnetoresistance and giant magnetoresistance effects have been ...
Mechanical reinforcement effects of carbon nanotube polymer composites
(Trinity College (Dublin, Ireland). School of Physics, 2004)
The effect of varying current density and pressure during arc-generation on the yield
and purity of multi walled carbon nanotube containing carbon soot has been studied
in this work. Various soots were produced and ...
Ultrafast spectroscopy of DNA binding systems
(Trinity College (Dublin, Ireland). School of Physics, 2004)
Ultrafast transient spectroscopy was used to investigate the properties of various systems which bind to DNA. Visible and IR pump and probe was employed to elucidate excited state process of the DNA binding complexes. Ultra ...
Kohlraush thermal relaxation in a random magnet
(American Physical Society, 1987)
Specific-heat measurements on amorphous FexZr100-x (x=90 and 92) by a thermal relaxation method reveal a temperature decay of the form T(t)=T0+T exp[-(t/)] below 20 K, where the alloys are asperomagnetically ordered. 0.5 ...
