Annealing of CoFeB/MgO based single and double barrier magnetic tunnel junctions: Tunnel magnetoresistance, bias dependence, and output voltage
(American Institute of Physics, 2009)
Co40Fe40B20/MgO single and double barrier magnetic tunnel junctions (MTJs) were grown using target-facing-target sputtering for MgO barriers and conventional dc magnetron sputtering for Co40Fe40B20 ferromagnetic electrodes. ...
Weyl points and exceptional rings with polaritons in bulk semiconductors
(2020)
Weyl points are the simplest topologically protected degeneracy in a three-dimensional dispersion relation. The realization of Weyl semimetals in photonic crystals has allowed these singularities and their consequences to ...
Optical reflectance anisotropy of buried Fe nanostructures on vicinal W(110)
(2007)
The optical anisotropy of Au protected Fe layers grown on a vicinal W(110) surface has been investigated using reflectance anisotropy spectroscopy (RAS). Iron nanostripes formed at submonolayer coverage, as well as Fe ...
Probing the out-of-plane optical response of plasmonic nanostructures using spectroscopic ellipsometry
(2011)
A simplified approach to investigate the out-of-plane response of plasmonic nanostructures using spectroscopic ellipsometry (SE) is presented. One-dimensional self-assembled arrays of Ag nanoparticles (NP?s) were grown on ...
New Methods of Studying Young Stellar Objects Using Radio Interferometry
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
While most studies of star formation are based on infrared or optical observations, radio astronomy has also proven very useful in the study of this process. This is seen for example in the detection of free-free emission ...
Tailoring highly conductive graphene nanoribbons from small polycyclic aromatic hydrocarbons: a computational study
(2013)
Pyrene, the smallest two-dimensional mesh of aromatic rings, with various terminal thiol substitutions, has been considered as a potential molecular interconnect. Charge transport through two terminal devices has been ...
Fine structure of coupled optical modes in photonic molecules
(2004)
We report on the coherent coupling of whispering gallery modes (WGM) in a photonic molecule formed
from two melamine-formaldehyde spherical microcavities with a thin shell of CdTe nanocrystals. Utilizing a
microporous ...
Distributions of certain market observables in an on-line betting exchange
(2011)
We analyze high frequency time series of odds and trading volume as extracted from markets on an on-line betting exchange, Betfair.com. As in financial markets, the probability distributions for the change in the market ...
X-ray spectroscopic studies of the electronic structure of chromium-based p-type transparent conducting oxides
(2016)
The valence band structure of p-type transparent oxides—crystalline MgxCr2−xO3 and nanocrystalline CuxCrOy—is analyzed as a function of incoming photon energy. The valence band of both p-type transparent conducting oxides ...
Resonant soft X-ray spectroscopic studies of certain transition metal oxides
(Trinity College (Dublin, Ireland). School of Physics, 2011)
Rutile-type transition-metal oxides are extremely fertile areas of study both for
fundamental and technological reasons due to the range of physical properties they
present, such as insulating TiO2, semiconducting Sn02 and ...
