Thermoreflectance Imaging of Semiconductor lasers with a Numerical Thermal Model
(2021)
High resolution surface temperature maps of a slotted
surface grating laser operating at approx. 1550 nm are obtained by
means of CCD-thermoreflectance imaging. The resolution is such
that the temperature of the 2 μm ...
Towards Reliable Benchmarking of Solar Flare Forecasting Methods
(2012)
Solar flares occur in complex sunspot groups, but it remains unclear how the probability of pro- ducing a flare of a given magnitude relates to the characteristics of the sunspot group. Here, we use Geostationary Operational ...
Measurement of nanotube content in pyrolytically generated carbon soot
(2000)
Carbon nanotubes can be efficiently separated from impurity
material in carbon soot using a conjugated polymer
filtration system as monitored by EPR, allowing the
calculation of purity of the crude carbon soot.
Size-dependent scaling of perpendicular exchange bias in magnetic nanostructures
(American Physical Society, 2007)
Size-dependent scaling is studied in exchange biased nanostructures obtained by depositing Pt/Co 3 /IrMn
multilayers with perpendicular magnetization onto an array of monodisperse polystyrene nanospheres with a
diameter ...
Production and processing of graphene and related materials
(IOP Publishing, 2020)
We present an overview of the main techniques for production and processing of graphene and
related materials (GRMs), as well as the key characterization procedures. We adopt a ‘hands-on’
approach, providing practical ...
Emission Properties of Colloidal Quantum Dots on Polyelectrolyte Multilayers
(2006)
We present steady state and time-resolved photoluminescence (PL) characteristics of differently charged CdTe quantum dots (QDs) adsorbed onto a polyelectrolyte (PE) multilayer. The PE multilayer is built up using a ...
Electrochemical energy storage properties of solution processed nanomaterial networks
(Trinity College (Dublin, Ireland). School of Physics, 2015)
Recently, exciting progress has been made towards the creation of electronic devices via unconventional fabrication routes. For example, liquid processing techniques such as printing and spraying are enabling the production ...
Whispering Gallery Mode Emission from a Composite System of CdTe Nanocrystals and a Spherical Microcavity
(2003)
We have studied the optical properties of a novel quantum dot?microcavity
system consisting of CdTe nanocrystals attached to a melamine
formaldehyde latex microsphere. The spheres were studied using
conventional and ...
Machine-learning semilocal density functional theory for many-body lattice models at zero and finite temperature
(2021)
We introduce a machine-learning density-functional-theory formalism for the spinless Hubbard model in one
dimension at both zero and finite temperature. In the zero-temperature case this establishes a one-to-one ...
Structural and tunneling properties of Si nanowires
(2013)
We investigate the electronic structure and electron transport properties of Si nanowires attached to Au electrodes from first principles using density functional theory and the nonequilibrium Green's function method. We ...
