Magnetism in dilute magnetic oxide thin films based on SnO2
(2006)
Thin films of SnO2 prepared by pulsed-laser deposition on R-cut sapphire substrates exhibit ferromagnetic properties at room temperature when they are doped with Cr, Mn, Fe, Co, or Ni, but not with other 3d cations. ...
Population inversion in a single InGaAs quantum dot using the method of adiabatic rapid passage
(2011)
Preparation of a speci c quantum state is a required step for a variety of proposed practical uses of
quantum dynamics. We report an experimental demonstration of optical quantum state preparation
in a semiconductor ...
Equilibrium shape of a bubble in a liquid-filled horizontal capillary
(2024)
Bubbles in liquid-filled capillaries feature in many practical applications. Here we describe the equilibrium shape
of a bubble in a horizontal capillary of circular cross section, as computed numerically using energy ...
Optical characterisation of blue-green-emitting polymer gain media : light amplification, laser emission, and two-photon absorption
(Trinity College (Dublin, Ireland). School of Physics, 2006)
Blue-green emitting stilbene dyes have been incorporated into different inert polymer hosts. Steady-state absorption and emission spectroscopy revealed a considerable host dependence of the spectroscopic properties of these ...
The Effects of Rotation on the Evolution of the First Stars in the Universe
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
Understanding the nature of the first stars is key to understanding the early Universe. With new facilities such as the James Webb Space Telescope we may soon have the first observations of the earliest stellar populations, ...
Large variations in both dark- and photoconductivity in nanosheet networks as nanomaterial is varied from MoS2 to WTe2
(2015)
We have used solution processing techniques to fabricate thin-film networks of nanosheets of six different transition metal dichalcogenides; MoS2, MoSe2, MoTe2, WS2, WSe2 and WTe2. We have measured both the dark conductivity ...
Optimisation of the synthesis and modification of CdTe quantum dots for enhanced live cell imaging
(Royal Society of Chemistry, 2006)
We report the preparation and luminescence enhancement of thioglycolic acid (TGA) stabilised
CdTe quantum dots (QDs) for use as live cell imaging tools in THP-1 macrophage cells. Short
irradiating times utilising a high ...
Magnetization of a Dy(Fe11Ti) single crystal
(American Physcial Society, 1990)
Magnetization curves have been measured in the temperature range from 4.2 to 300 K along the [100], [110], and [001] directions of a Dy(Fe11Ti) single crystal in fields up to 7 T. The magnetic moment is along [100] below ...
Galaxy clusters, voids and elliptical galaxies using the ROSAT PSPC
(Trinity College (Dublin, Ireland). School of Physics, 2003)
The ROSAT data archive contains of the order of 100,000 sources observed by the ROSAT PSPC (Position Sensitive Proportional Counter). For many sources detected with the ROSAT PSPC there is not a sufficient number of
photons ...
