Data-driven enhancement of cubic phase stability in mixed-cation perovskites
(2021)
Mixing cations has been a successful strategy in perovskite synthesis by solution-processing, delivering improvements in the thermodynamic stability as well as in the lattice parameter control. Unfortunately, the relation ...
Förster resonant energy transfer in quantum dot layers
(2010)
Förster resonant energy transfer (FRET) in quantum dot (QD) layer structures has been analyzed. Small and large colloidal CdTe QDs were used as donors and acceptors, respectively. A FRET theory for random donor/acceptor ...
Non-resonant wavelength modulation saturation spectroscopy in acetylene-filled hollow-core photonic bandgap fibres applied to modulationfree laser diode stabilisation
(2009)
In this paper the application of Wavelength Modulation (WM)
techniques to non-resonant saturation spectroscopy
in acetylene-filled
Hollow-Core Photonic Bandgap Fibres (HC-PBFs) and m

High-Figure-of-Merit Biosensing and Enhanced Excitonic Absorption in an MoS2-Integrated Dielectric Metasurface
(2023)
Among the transitional metal dichalcogenides (TMDCs), molybdenum disulfide (MoS2) is considered an outstanding candidate for biosensing applications due to its high absorptivity and amenability to ionic current measurements. ...
Anomalous anisotropic magnetoresistance in epitaxial Fe3O4 thin films on MgO (100)
(American Physical Society, 2008-12)
Studies of the angular dependence of the anisotropic magnetoresistance (AMR) are reported for epitaxial films of magnetite (Fe3O4) grown on MgO(001) and also for single crystals of magnetite. The characteristic feature of ...
Spin-polarized transport through single-molecule magnet Mn6 complexes
(2013)
The coherent transport properties of a device, constructed by sandwiching a Mn6 single-molecule magnet between two gold surfaces, are studied theoretically by using the non-equilibrium Green's function approach combined ...
Polarisation Dependent Dynamics in Bulk Semiconductor Optical Amplifiers
(2006)
A free space contra-propagation set-up is implemented and a dynamic pump-probe study of the eigenmodes of a SOA in the picosecond regime is undertaken. The time-resolved probe transmission of the TE and TM modes of the ...
Investigating of gas sensing and diode laser frequency stabilisation using novel photonic microstructures
(Trinity College (Dublin, Ireland). School of Physics, 2010)
Laser spectroscopy is nowadays a widespread research field with countless
applications across multiple disciplines. In particular, the application to gas sensing
in the near-infrared region significantly benefits from the ...
Dielectric anomalies and spiral magnetic order in CoCr2 O4
(American Physical Society, 2006)
We have investigated the structural, magnetic, thermodynamic, and dielectric properties of polycrystalline CoCr2 O4, an insulating spinel exhibiting both ferrimagnetic and spiral magnetic structures. Below Tc =94 K the ...
