Compact 2-D FDTD Method Combined With Pad Approximation Transform for Leaky Mode Analysis
(2010)
Leaky mode analysis has been carried out based on the compact 2-D finite-difference time-domain (FDTD) method combined with the uniaxial anisotropic perfectly matched-layer (UPML) absorption boundary condition and the Pade ...
Simultaneous observation of direct and Raman-scattered O VI lines in the symbiotic nova RR telescopii
(American Astronomical Society, 1995)
The optical spectra of some symbiotic binaries show two lines in the red region of the spectrum that cannot be identified with any known allowed or forbidden transitions. A case has been made that these lines are Raman-scattered ...
Investigation of transport through interfacial barriers between metals and semiconductors
(Trinity College (Dublin, Ireland). School of Physics, 2009)
Electrical spin injection from a ferromagnetic metal source into a semiconductor can
only take place through an interfacial barrier (Rashba, Phys. Rev. B 62, R16267 and
Phys. Rev. B 68, 241310). This thesis presents a study ...
Control led sequential dehydrogenation of single molecules by scanning tunneling microscopy
(2010)
Scanning tunneling microscopy
STM
is today the most powerful and versatile tool available for imaging
and manipulating single molecules on surfaces. Here, we explore its ultimate limit by demonstrating the
possibility ...
Exfoliation of 2D materials by high shear mixing
(2019)
While it has been demonstrated that large scale liquid exfoliation of graphene is possible using high-shear exfoliation, it has not yet been shown to be applicable to a broader range of layered materials. In addition, it ...
Probing outflows from young stars and brown dwarfs
(Trinity College (Dublin, Ireland). School of Physics, 2005)
The phenomenon of mass outflow from young stellar objects, is arguably the
most spectacular stage in the formation of a star. Much is known about the large
scale manifestations of outflows and many breathtaking images ...
Monte Carlo study of dilute magnetic semiconductors
(Trinity College (Dublin, Ireland). School of Physics, 2009)
This thesis is primarily concerned with the development and testing of various models
explaining the magnetic properties of semiconducting oxides doped with highly dilute
concentrations of a magnetic impurity. Taking ZnO:Co ...
Pulsed laser ablation of silver: ion dynamics in plasma plume
(2010)
The ion dynamics of silver ablated using 355 and 193nm pulsed laser irradiation in vacuum has been investigated by using
a Langmuir probe and quadrupole mass spectrometry. The kinetic energies of the ablated silver ions ...
Spectroscopic Identification of the Charge Transfer State in Thiophene/Fullerene Heterojunctions: Electroabsorption Spectroscopy from GW/BSE Calculations
(2023)
Creation of charge transfer (CT) states in bulk heterojunction systems such as C60/polymer blends is an
important intermediate step in creation of carriers in organic photovoltaic systems. CT states generally have ...
Stability and motion of foams and films in confined geometries
(Trinity College (Dublin, Ireland). School of Physics, 2005)
The last 20 years of research in the physics of foams display the development of a thorough
understanding of dry and static foams. In the realm of wet and dynamic foams, however, many interesting and puzzling effects have ...
