Physical models of infant mortality: implications for defects in biological systems
(2020)
Reliability engineering concerned with failure of technical inanimate systems usually uses the vocabulary and notions of human mortality, e.g., infant mortality vs. senescence mortality. Yet, few data are available to ...
Implications of antiphase boundaries (APBs) on the strain relaxation and magnetotransport properties of Fe3o4 hetero-epitaxial thin films
(Trinity College (Dublin, Ireland). School of Physics, 2007)
The strain relaxation and magneto transport properties of epitaxial
magnetite (Fe3O4) thin films were studied. Epitaxial Fe3O4 film s were grown
on MgO and MgAl2O4 substrates using an Oxygen plasma assisted Molecular
beam ...
The preparation of hybrid films of carbon nanotubes and nanographite/graphene with excellent mechanical and electrical properties
(2010)
We have prepared mixed dispersions of single walled nanotubes and nano-graphite / graphene in the solvent N-methyl pyrrolidone. This allows the deposition of hybrid films by vacuum filtration. Scanning electron microscopy ...
Polarization dependence of a GaAs-based two-photon absorption microcavity photodetector
(2008)
In this paper, the polarization response of a GaAs based twophoton
absorption microcavity photodetector has been studied. The
deviation in the dependence of the detector response from that of bulk GaAs
is shown to be ...
Organic light-emitting diodes and photovoltaic devices: Incorporation of carbon nanotubes as charge transport media
(Trinity College (Dublin, Ireland). School of Physics, 2003)
The effects of incorporating multi-walled carbon nanotubes (MWNT) in two existing functional organic devices : organic light emitting diodes (OLEDs) and organic solar cells have been studied. Single layer OLEDs and organic ...
Development and Characterisation of a Zero-Moment Half-Metal
(Trinity College Dublin. School of Physics. Discipline of Physics, 2021)
A dream material for spintronics would have low/zero net moment, no stray fields, high resonance frequency, low damping and be 100 % spin polarised. Such materials combine the best features of a ferromagnet and an ...
Plasmon resonance studies in silver nanoparticles arrays grown by Atomic Terrace Low Angle Shadowing (ATLAS)
(Trinity College (Dublin, Ireland). School of Physics, 2009)
Nanotechnology refers to the study of nanomaterials aiming to understand the physical properties and phenomena that materials show at the nanometre scale. A key goal in nanotechnology is acquiring the ability to manipulate ...
Giant energy product in nanostructured two-phase magnets
(American Physical Society, 1993)
Exchange hardening of nanostructured two-phase systems composed of an aligned hard phase and a soft phase with high magnetization is investigated using an approach which yields analytic nucleation fields from the micromagnetic ...
Spontaneous Emission and Energy Transfer Rates Near a Coated Metallic Cylinder
(2014)
The spontaneous emission and energy transfer rates of quantum systems in proximity to a dielectrically coated metallic cylinder are investigated using a Green's tensor formalism. The excitation of surface plasmon modes can ...
Equipartition of Energy Defines the Size-Thickness Relationship in Liquid-Exfoliated Nanosheets.
(2019)
Liquid phase exfoliation is a commonly used method to produce 2D nanosheets from a range of layered crystals. However, such nanosheets display broad size and thickness distributions and correlations between area and ...
