Highly emissive nanowires grown from CdTe nanocrystals in a phosphate buffer solution
(2005)
We present details on the CdTe nanowires formation, which were found to grow in a standard
physiological phosphate-buffered solution, including in-situ observation of growth with a confocal
microscope. The choice of ...
Quantitative determination of the adsorption site of the OH radicals in the H2O/Si(100) system
(2002)
Using scanned-energy mode photoelectron diffraction from the O 1s level, the local structure around the adsorbed OH species resulting from the interaction of H2O with a Si(100)(2 ? 1) has been determined, by a combination ...
Towards stable molecular nanostructures on a semiconductor surface
(Trinity College (Dublin, Ireland). School of Physics, 2012)
The miniaturisation trend in the construction of electronic devices has recently sparked an
interest in the bottom-up construction of 2-dimensional nanostructures from single organic
molecular building blocks on surfaces. ...
Anomalous I-V curve for mono-atomic carbon chains
(2010)
The electronic transport properties of mono-atomic carbon chains were studied theoretically using a combination of density functional theory and the non-equilibrium Green's functions method. The I?V curves for the chains ...
Intrinsic decoherence mechanisms in the microcavity polariton condensate
(American Physical Society, 2008)
The fundamental mechanisms which control the phase coherence of the polariton Bose-Einstein
condensate (BEC) are determined. It is shown that the combination of number fluctuations and
interactions leads to decoherence ...
Influence of exchange bias on magnetic losses in CoFeB/MgO/CoFeB tunnel junctions

Method of increasing spatial resolution of the scanning near-field microwave microscopy
(2003)
In this article we propose methods for the measurement of electric intensity of a microwave field above the surface of microwave circuits. Using miniaturized coaxial antennas and a special probe positioning system, we ...
High Selectivity and Sensitivity in Chemiresistive Sensing of Co(II) Ions with Liquid-Phase Exfoliated Functionalized MoS2: A Supramolecular Approach
(2023)
Chemical sensing of water contamination by heavy metal ions is key as it represents a most severe environmental problem. Liquid-phase exfoli-ated two-dimensional (2D) transition metal dichalcogenides (TMDs) are suitable ...
Computational design of magnetic molecules and their environment using quantum chemistry, machine learning and multiscale simulations
(2022)
Having served as playground for fundamental studies on the physics of d and f
electrons for almost a century, magnetic molecules are today becoming increasingly
important for technological applications, such as magnetic ...
Electronic transport and magnetic properties of organic semiconductors
(Trinity College (Dublin, Ireland). School of Physics, 2011)
The primary aim of this research thesis is to investigate the electronic transport and
magnetic properties of organic semiconducting materials. Undeniably, experimental and
theoretical work is needed to conclusively study ...
