Characterisation and Manipulation of Transition Metal Dichalcogenides via Atomic Force Microscopy
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
Scanning probe microscopy (SPM) has revolutionised nanotechnology and allowed the study and manipulation of materials at the nanoscale, making it ideal for the study of solid-state physics and semiconductor technologies. ...
A direct-write, resistless hard mask for rapid nanoscale patterning of diamond
(2011)
We introduce a simple, resist-free dry etch mask for producing patterns in diamond, both bulk and thin deposited films. Direct gallium ion beam exposure of the native diamond surface to doses as low as 1016 cm-2 forms a ...
Stimulated spin dynamics of polaritons in semiconductor microcavities
(American Physical Society, 2002)
Time-resolved polarization spectroscopy of polariton pair scattering in semiconductor microcavities enables
complete measurement of the polariton spin dynamics. In addition to spin-preserving interactions previously
reported, ...
Extracting the hysteresis loops of magnetic interfaces from optical second-harmonic intensity measurements
(2007)
Surface- and interface-sensitive optical techniques, such as optical second-harmonic generation (SHG), allow the buried interfacial structure of centrosymmetric materials to be explored through thin capping layers, and ...
Defect engineering of ultra-thin layered molybdenum disulfide towards novel memristive and optoelectronic applications
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)
In the ever-evolving field of nanoelectronics, new paradigms are constantly sought-after to improve the performance of next-generation circuit components. In the last decade, two-dimensional (2D) semiconductors have emerged ...
Short pulse transmission characteristics in multi-contact SOA
(2012)
An experimental characterisation of a multi-contact semiconductor optical amplifier using ultrashort optical pulses is presented. The SOA in question allows the injection of bias current through ...
Electronic transport on carbon nanotube networks : a multiscale computational approach
(Trinity College (Dublin, Ireland). School of Physics, 2011)
Carbon is arguably the most versatile of chemical elements. For the last 25 years
research on carbon nanostrutures has been one of the most active areas of science.
Carbon-based nanoelectronics is the most promising ...
Origin of electrophosphorescence from a doped polymer light emitting diode
(2001)
The origin of electrophosphorescence from a doped polymer light emitting diode(LED)has been investi-
gated. A luminescent polymer host, poly (9,9-dioctylfluorene)(PFO), was doped with a red phosphorescent dye, ...
Dynamic structural colur in thin film stacks and patterned nanoparticle arrays
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
In this thesis a number of metal nanostructures have been investigated for structural colour at sub-micron scales. These structures have utilised localised surface plasmon resonance (LSPR) to produce near-field interactions ...
Atomistic simulations of highly conductive molecular transport junctions under realistic conditions
(2013)
We report state-of-the-art atomistic simulations combined with high-fidelity conductance calculations to probe structure–conductance relationships in Au–benzenedithiolate (BDT)–Au junctions under elongation. Our results ...
