Solution phase silver nanostructures for ehanced localized surface plasmonic sensing
(Trinity College (Dublin, Ireland). School of Physics, 2010)
A detailed study of the Localized Surface Plasmon Resonances (LSPR) of a range
of solution phase silver nanostructure sols and their refractive index sensitivity is
presented. This work focuses on developing a thorough ...
Variable range of the RKKY interaction in edged graphene
(2014)
The indirect exchange interaction is one of the key factors in determining the overall alignment of magnetic impurities embedded in metallic host materials. In this work we examine the range of this interaction in ...
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 ...
Local inversion of the chemical environment representations
(2022)
Machine-learning generative methods for material design are constructed by representing a given chemical structure, either a solid or a molecule, over appropriate atomic features, generally called structural descriptors. ...
Near-infrared luminescent polymer amplifiers and microlasers
(Trinity College (Dublin, Ireland). School of Physics, 2008)
Near-infrared optical gain in luminescent polymeric slab asymmetric waveguides has been investigated by use of amplified spontaneous emission. Upon nanosecond photopumping, the waveguides have shown a small-signal gain ...
Heating and compression of a laser produced plasma in a pulsed magnetic field
(2016)
A pulsed 0.3 T magnetic field was used to heat and compress a low-temperature laser produced copper plasma. The magnetic field was generated using a planar 3-turn coil positioned 10 mm above the ablation spot. The plasma ...
Electronic properties of doped carbon-based nanostructures
(Trinity College (Dublin, Ireland). School of Physics, 2016)
Carbon-based nanostructures have been at the forefront of scientific research for the last couple of decades due to their unique properties, giving rise to many potential applications especially for electronics. Their ...
On the control of quantum many-body systems
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
The ability to control and actively manipulate physical systems at a scale at which quantum properties manifest themselves is crucial for the development of quantum technologies.
While, at present, it is possible to ...
Multiprobe quantum spin Hall bars
(2014)
We analyze electron transport in multiprobe quantum spin Hall (QSH) bars using the B¨uttiker
formalism and draw parallels with their quantum Hall (QH) counterparts. We find that in a QSH
bar the measured resistance changes ...
Electronic and structural characterisation of polycrystalline platinum disulfide thin films
(2020)
We employ a combination of scanning tunnelling microscopy (STM) and scanning tunnelling spectroscopy (STS) to investigate the properties of layered PtS2, synthesised via thermally assisted conversion (TAC) of a metallic ...
