Precise modification of 2D materials by gas ion beams
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
Fermi level spin polarization of polycrystalline thulium by point contact Andreev reflection spectroscopy
(2011)
The spin polarization near the Fermi level in bulk polycrystalline ferrimagnetic thulium is
investigated by means of point contact Andreev reflection (PCAR), in the temperature interval
(1.9?9.2 K). The highest polarization ...
Search for magnets with properties intermediate between Nd-Fe-B and Ferrite
The rare earth elements neodymium, samarium, terbium and dysprosium are predominantly mined in China (>95%) there wild prices fluctuations in 2011 as a result of Chinese government policies undermined confidence in the ...
Layer-dependent reactivity in the Fe/Mo(110) epitaxial ultrathin film system
(2003)
Fe films in the 0.4<~?<~4.7ML (monolayer) coverage range were deposited on a Mo(110) substrate at temperatures between 300 K and 700 K, under ultrahigh vacuum conditions. The adsorption of CO, CO2, H2O, and O2 onto these ...
Self-assembled alkali and alkaline earth metal nanopatterns on Fe3O4(001)
(2004)
We have studied the mechanism of nanopattern formation by self-assembly of impurities aggregated on the Fe3O4(001) surface. Self-assembly was controlled by thermal diffusion from the bulk of natural and artificial single ...
An investigation into the effects of magnetic fields on biological cell processes
(Trinity College (Dublin, Ireland). School of Physics, 2011)
The application of external magnetic fields to biological cells has received the attention of many
researchers in recent decades and there have been countless reports of effects on a myriad of
cellular processes. Despite ...
The effects of percolation in nanostructured transparent conductors
(2011)
Networks of nanoscale conductors such as carbon nanotubes, graphene, and metallic nanowires are promising candidates to replace metal oxides as transparent conductors. However, very few previous reports have described ...
Electron and spin injection in short-channel organic semiconducting devices
(Trinity College (Dublin, Ireland). School of Physics, 2012)
The realization of an active device that combines electric control of the source-drain current, as in transistors, with the memory effect of spin valves, has long been sought for the next generation spin electronics. The ...
Solvent Exfoliation of Transition Metal Dichalcogenides: Dispersibility of Exfoliated Nanosheets Varies Only Weakly between Compounds
(2012)
We have studied the dispersion and exfoliation of four inorganic layered compounds, WS2,
MoS2, MoSe2 and MoTe2 in a range of organic solvents. The aim was to explore the relationship
between the chemical structure of the ...
Red giant mass-loss : studying evolved stellar winds with FUSE and HST / STIS
(Trinity College (Dublin, Ireland). School of Physics, 2006)
The changes that a star undergoes during the dying process are the most dramatic of its lifetime. These changes result in the most important interactions between a star and its environment, indeed it is in this area of ...
