Passive thin film circuits of nanomaterials, inkjet printed on flexible temperature sensitive substrates
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
The objective of my work is threefold, firstly, to prepare functional ink dispersions of nanomaterials at high concentration with a well-defined narrow size distribution; secondly, to pattern low resistance, semiconducting ...
Rotational transitions in a C60 monolayer on the WO2/W(110) surface
(2011)
Variable-temperature scanning tunneling microscopy (STM) is shown to be an effective technique to study two-dimensional phase transitions. Observations show that a monolayer of C60 deposited on an ultrathin WO2 layer grown ...
Generalizing solubility parameter theory to apply to one- and two-dimensional solutes and to incorporate dipolar interactions
(2013)
Hildebrand and Hansen solubility parameters are commonly used to identify suitable solvents for the dispersion or dissolution of a range of solutes, from small molecules to graphene. This practice is based on a number of ...

Cylindrical permanent-magnet structures using images in an iron shield
(IEEE, 2003)
We report on cylindrical permanent-magnet structures that exploit the image effect in a surrounding circular soft-iron sheath. We present the theory for a general multipole ring, where the polarization direction ? = (n + ...
Inverted magnetoresistance in dual spin valve structures with a synthetic antiferromagnetic free layer
(2009)
We report an oscillation of the giant magnetoresistance GMR ratio as a function of Ru layer
thickness in the CoFe/Cu/ CoFe/Ru/CoFe SAF/Cu/CoFe/IrMn dual spin valve SV structure. A
normal GMR with a positive sign is ...
Highly-efficient optical sampling based on two-photon absorption in a semiconductor micro-cavity device
(2005)
We demonstrate a highly-efficient optical sampling system based upon the nonlinear process of two-photon absorption in a specially designed semiconductor microcavity. The sensitivity of the system is around 0.1 mW/sup 2/ ...
Nonreciprocal quantum transport at junctions of structured leads
(2019)
We propose and analyze a mechanism for rectification of spin transport through a small junction between two spin baths or leads. For interacting baths, we show that transport is conditioned on the spacial asymmetry of the ...
