Continuous wafer-scale graphene on cubic-SiC(001
(2013)
The atomic and electronic structure of graphene synthesized on commercially available cubic-SiC(001)/Si(001) wafers have been studied by low energy electron microscopy (LEEM), scanning tunneling microscopy (STM), low energy ...
Thulium doped ZBLAN fibre ring-cavity amplifier
(2005)
We have demonstrated the integration of supporting lasing at 1.88 ?m for enhancing the gain in a thulium doped
ZBLAN amplifier. The laser ring cavity has been created in order to reduce the bottleneck effect caused by the ...
Population inversion in quantum dot ensembles via adiabatic rapid passage
(2010)
Electrical detection of adiabatic rapid passage (ARP) in quantum dot ensembles is explored by extension of a simple physical model. We include exciton and biexciton states and model the current flow into the external circuit ...
Star formation : the generation and propagation of jets from young stars
(Trinity College (Dublin, Ireland). School of Physics, 2006)
While much progress has been made in recent decades, there are many outstanding
questions about the star formation process, including how jets/outflows from young stars
are launched and travel away from their source. This ...
Enhanced coupling of electronic and photonic states in a microcavity-quantum dot system
(2005)
Spherical microcavities consisting of a dielectric material show unique optical characteristics as resonators in combination with semiconductor nanoparticles. A high quality factor results in a very narrow bandwidth of the ...
Influence of antiphase boundary density on the conduction noise properties of epitaxial magnetite thin films
(2005)
Low frequency conduction noise (1/f noise) properties of epitaxial magnetite (Fe3O4) thin films having a varying density of antiphase boundaries (APBs) were investigated as a function of temperature and frequency. Temperature ...
Long-chain amine-templated synthesis of gallium sulfide and gallium selenide nanotubes
(2016)
We describe the soft chemistry synthesis of amine-templated gallium chalcogenide nanotubes through the reaction of gallium(iii) acetylacetonate and the chalcogen (sulfur, selenium) using a mixture of long-chain amines ...
Using steps at the Si-SiO2 interface to test simple bond models of the optical second-harmonic response
(2007)
A simple bond model of the optical second-harmonic (SH) response from interfaces, which assumes a single axial component for each bond, is tested by comparing the response from different step structures at the Si?SiO2 ...
