Towards data-driven next-generation transmission electron microscopy
(2020)
Electron microscopy touches on nearly every aspect of modern life, underpinning materials development for quantum computing, energy and medicine. We discuss the open, highly integrated and data-driven microscopy architecture ...
Combining ϵ-Near-Zero Behavior and Stopped Light Energy Bands for Ultra-Low Reflection and Reduced Dispersion of Slow Light
(2017)
We investigate media which exhibits epsilon-near-zero (ENZ) behavior while simultaneously sustaining
stopped light energy bands which contain multiple points of zero group velocity (ZGV). This allows
the merging of ...
A theoretical study of the strain-modified RKKY interaction in magnetically doped carbon materials
(Trinity College (Dublin, Ireland). School of Physics, 2015)
Graphene-related materials continue to be in the scientific limelight due to near-continuous discoveries regarding their properties and production. The applications envisaged for these super materials are numerous and ...
First-principles prediction of polar half-metallicity and out-of-plane piezoelectricity in two-dimensional quintuple layered cobalt selenide
(2021)
Polar half-metals, possessing both polarity and half-metallicity, may have potential as media in novel spintronic quantum devices, but they have never been reported in the two-dimensional (2D) form. By combining the particle ...
Atomic row doubling in the STM images of Cu(014)-O obtained with MnNi tips
(2007)
We report on scanning tunneling microscopy studies of the Cu(014)-O surface using MnNi tips. Remarkably, the results show a regular apparent doubling of surface atomic rows in the {110} direction. A qualitative explanation ...
In-band OSNR monitoring using a pair of Michelson fiber interferometers
(2010)
Two polarization-independent Michelson fiber inter
ferometers
with different optical delays were used to measure
the in-band OSNR of an
optical signal from 5 to 30dB within an accuracy of
0.5dB. Using an
expansion ...
Exposition of semiconducting and ferromagnetic properties of pulsed-laser-deposited thin films of LaFe1-xNixO3 (x=0.3, 0.4, and 0.5)
(American Institute of Physics, 2005)
We have explored the possibility of ferromagnetic semiconducting property in the epitaxial thin
films of LaFe1?xNixO3 x=0.3, 0.4, and 0.5 grown on 001 oriented LaAlO3 substrate. We observe
that substitution of Ni in ...
Z-Cone model for the energy of an ordered foam
(2014)
We develop the Z-Cone Model, in terms of which the energy of a foam may be estimated. It is directly applicable to an ordered structure in which every bubble has Z identical neighbours. The energy (i.e. surface area) may ...
Decay Rates near layers of Au Nanospheres
(2012)
The decay rate of quantum emitters near a layer of Au nanospheres is studied in the framework of a Green’s
tensor formalism. The localized surface plasmons that can be excited on the gold spheres provide a strong avenue
for ...
