Third-order Nonlinear Optical Response and Ultrafast Carrier Dynanics of 2D Materials
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
Two dimensional (2D) materials have been in the spotlight of scientific researchers in the last decade due to their outstanding chemical, physical, electronic, mechanical and optical properties in comparison to their bulk. ...
Noise controlled semiconductor optical amplifier based on lateral cavity laser
(2010)
Experimental characterisation of a novel noise-controlled semiconductor optical amplifier (NCSOA) is presented. The design utilises grooves etched parallel to the active waveguide, at the output sections of the NCSOA, so ...
Charge ordering on the surface of Fe3O4(001)
(2002)
We have studied the (001) surface of a Fe3O4 single crystal using scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), and Auger electron spectroscopy. A clean surface was obtained by a combination ...
Design and Construction of an Optoelectronic. Crossbar Switch Containing a Terabit per. Second Free-Space Optical Interconnect
(1999)
THE COMPLETED DETAILED DESIGN AND INITIAL PHASES OF CONSTRUCTION OF AN OPTOELECTRONIC CROSSBAR DEMONSTRATOR ARE PRESENTED. THE EXPERIMENTAL SYSTEM USES HYBRID VERY LARGE SCALE INTEGRATED OPTOELECTRONICS TECHNOLOGY WHEREBY ...
Hydrogen in R2Fe17 intermetallic compounds: structural, thermodynamic and magnetic properties
(American Physcial Society, 1997)
The absorption and diffusion behavior of hydrogen in iron-rich rare-earth intermetallics of the type
R2Fe17 (R5Y, Sm, Gd! and the resulting changes of their magnetic properties are investigated. Intermediate
hydrogen ...
Highly-efficient optical sampling of a 100 Gbit/s OTDM data signal via two-photon absorption in a semiconductor microcavity
(2005)
By incorporating a semiconductor microcavity device, a highly-efficient two-photon absorption based sampling system, with a system sensitivity of 0.009 mW/sup 2/ and temporal resolution <500 fs is presented.
Plasmonic interactions of gold nanoparticles with photoluminescent materials
(Trinity College Dublin. School of Physics. Discipline of Physics, 2024)
The variable plasmonic resonances of metal nanoparticles have many applications across a wide range of fields, including the modification of the emission of photoluminescent materials. The plasmonic interactions of gold ...
Conductance enhancement due to interface magnons in electron-beam evaporated MgO magnetic tunnel junctions with CoFeB free layer deposited at different pressure
(2014)
Electron-beam evaporated MgO-based magnetic tunnel junctions have been fabricated with the
CoFeB free layer deposited at Ar pressure from 1 to 4 mTorr, and their tunneling process has been
studied as a function of ...
Application of single crystalline tungsten for fabrication of high resolution STM probes with controlled structure
(2011)
The possibility to fabricate scanning tunneling microscopy (STM) probes with controlled electronic structure using single crystalline tungsten tips is discussed. High resolution power of oriented single crystalline probes ...
Science and technology roadmap for graphene, related two-dimensional crystals, and hybrid systems
(2015)
We present the science and technology roadmap for graphene, related two-dimensional crystals, and hybrid systems, targeting an evolution in technology, that might lead to impacts and benefits reaching into most areas of ...
