Morphology and strain-induced defect structure of ultrathin epitaxial Fe films on Mo(110)
(2002)
Fe films in a coverage range of 0.4<~?<~4.7ML were deposited on a Mo(110) substrate in the 300<~T<~700K temperature range. It is found that growth around 300 K is mediated by the step-flow growth mechanism, in contrast ...
Resonant Soft X-Ray Inelastic Scattering and Soft X-Ray Emission Study of the Electronic Structure of alpha-MoO3
(2009)
The electronic structure of quasi-low-dimensional solids is a topic of enduring interest due to the complex
many-body interactions that exist in such materials and their resulting exotic physical properties. A well ...
Surface studies of magnetite (100)
(Trinity College (Dublin, Ireland). School of Physics, 2000)
The (100) surface of magnetite (Fe3 O4 ) has been studied using scanning
tunneling microscopy (STM) in ultra high vacuum (UHV) with a view to
establishing a test surface for spin polarised STM experiments. Two ...

Plume dynamics in nanosecond and femtosecond laser ablation of metal
(Trinity College (Dublin, Ireland). School of Physics, 2010)
This thesis examines the ablation plume produced from nanosecond and
femtosecond laser ablation of metal targets in vacuum. Optical emission and absorption spectroscopy, a time-of-flight Langmuir ion probe and ablation ...
Study of the properties of networks of low-dimensional nanomaterials for transparent flexible device applications
(Trinity College (Dublin, Ireland). School of Physics, 2013)
Transparent conductors (TC) - materials that are both transparent and conductive - are of great interest for modern technologies. However, a replacement is needed for the most commonly used TC, Indium tin oxide (ITO), ...
Persistent current and Drude weight for the one-dimensional Hubbard model from current lattice density functional theory
(2012)
The Bethe ansatz local density approximation (LDA) to lattice density functional theory (LDFT) for the one-dimensional repulsive Hubbard model is extended to current-LDFT (CLDFT). The transport properties of mesoscopic ...
Quantum heat statistics with time-evolving matrix product operators
(2021)
We present a numerically exact method to compute the full counting statistics of heat transfer in non-Markovian open quantum systems, which is based on the time-evolving matrix product operator algorithm. This approach is ...
Atomic coordination and the distribution of electric field gradients in amorphous solids
(American Physical Society, 1981)
The observation of nuclear quadrupole interactions in amorphous solids provides a unique possibility of obtaining information about the angular distribution of local ionic coordinations, complementary to the information ...
