Thickness dependence of the effective damping in epitaxial Fe3O4/MgO thin films
(2011)
The precessional magnetization dynamics of high quality epitaxial magnetite (Fe3O4) thin films growth on MgO are investigated by inductive magnetization dynamic measurements in time and frequency domain. An upper bound for ...
Transparent conducting oxide based devices
(Trinity College (Dublin, Ireland). School of Physics, 2011)
Transparent conducting oxide (TCO) materials, formerly regarded as degenerate conductors of only one carrier type, can now be considered as transparent semiconductors possessing the potential for integration into more ...
Wannier-function-based constrained DFT with nonorthogonality-correcting Pulay forces in application to the reorganization effects in graphene-adsorbed pentacene
(2018)
Pulay terms arise in the Hellmann-Feynman forces in electronic-structure calculations when one employs a basis set made of localized orbitals that move with their host atoms. If the total energy of the system depends on a ...
Raman spectra of p-type transparent semiconducting Cr<inf>2</inf>O<inf>3</inf>:Mg
(2015)
Abstract
We present an analysis of the Raman spectra of p-type transparent conducting Cr2O3:Mg grown by various techniques including spray pyrolysis, pulsed laser deposition, molecular beam epitaxy and reactive magnetron ...
Critical field behavior and antiband instability under controlled surface electromigration on Si(111)
(2011)
In this study we investigate step bunching and antiband surface instabilities on Si(111). We experimentally study the effects of a controlled electromigration field on the onset of antibands. We analyze the initial stage ...
Issues relating to the application of monolithic tuneable laser diodes to multi-species gas detection
(Trinity College (Dublin, Ireland). School of Physics, 2005)
Tuneable Diode Laser Absorption Spectroscopy (TDLAS) technology for gas sensing
has had reliance on, and has benefited from, devices developed for the optical
communications sector, namely distributed feedback laser diodes. ...

Ground state of a spin-crossover molecule calculated by diffusion Monte Carlo
(2013)
Spin-crossover molecules have recently emerged as a family of compounds potentially useful for implementing
molecular spintronics devices. The calculations of the electronic properties of such molecules is a formidable

Inkjet deposition of liquid-exfoliated graphene and MoS2 nanosheets for printed device applications
(2014)
Here we demonstrate inkjet printing of nanosheets of both graphene and MoS2 prepared by liquid exfoliation. We describe a protocol for the preparation of inks of nanosheets with well-defined size distribution and concentration ...
An experimental investigation of tunable laser diodes based on multiple etched slots
(Trinity College (Dublin, Ireland). School of Physics, 2010)
Widely tunable semiconductor lasers will play a critical part in future
technologies. Tunable lasers are rapidly replacing fixed wavelength lasers in dense
wavelength division multiplexing (DWDM) optical communications. ...
