Lattice distortion effects on the magneto-structural phase transition of MnAs.
(2005)We present a systematic experimental and theoretical study of the first-order phase transition of epitaxially grown MnAs thin films under biaxial tensile stress. Our results give direct information on the dependence of 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 ... -
LEMUR: Large European Module for solar Ultraviolet Research. European contribution to JAXA's Solar-C mission
(2012)Understanding the solar outer atmosphere requires concerted, simultaneous solar observations from the visible to the vacuum ultraviolet (VUV) and soft X-rays, at high spatial resolution (between 0.1" and 0.3"), at high ... -
LEMUR: Large European module for solar Ultraviolet Research: European contribution to JAXA's Solar-C mission
(2012)The solar outer atmosphere is an extremely dynamic environment characterized by the continuous interplay between the plasma and the magnetic field that generates and permeates it. Such interactions play a fundamental role ... -
Light amplification and lasing in a (meta-phenylene vinylene) copolymer
(2003)We report on single pass optical gain and lasing measurements on a blue-emitting copolymer, poly ~ m -phenylene vinylene-co-2,5-dioctyloxy- p -phenylene vinylene ! under 0.5 ns pulsed photoexcitation. This soluble ... -
The Limit of Spin Lifetime in Solid-State Electronic Spins
(2020)The development of spin qubits for quantum technologies requires their protection from the main source of finite-temperature decoherence: atomic vibrations. Here we eliminate one of the main barriers to the progress in ... -
Linear and nonlinear optical characterisation of self assembled nanostructures

Linear and nonlinear optical characterisation of silicon nanowire structures
(Trinity College (Dublin, Ireland). School of Physics, 2008)The morphological and optical properties of various silicon nanowire structures were investigated. Photoluminescence was produced by all of the nanostructures and was attributed to a variety of different mechanisms. Optical ... -
Linear and nonlinear optical properties of low-dimensional structures on vicinal silicon (111) surfaces
(Trinity College (Dublin, Ireland). School of Physics, 2008) -
Linear and nonlinear waveguiding in Rhodamine-doped
(1991)Planar waveguiding of 350-ps pulses, at a wavelength in the region of the long-wavelength tail of the absorption, is observed by coupling by prism into spun films of Rhodamine-B-doped epoxy films. In a 13-?.m-thick film, ... -
Linear Jacobi-Legendre expansion of the charge density for machine learning-accelerated electronic structure calculations
(2023)As the go-to method to solve the electronic structure problem, Kohn-Sham density functional theory (KS-DFT) can be used to obtain the ground-state charge density, total energy, and several other key materials’ properties. ... -
Linewidth enhancement factor and modulation bandwidth of lattice matched 1.5 micron InGaAsN/GaAs quantum well lasers
(SPIE, 2004)The linewidth enhancement factors of lattice-matched 1.5 ?m wavelength InGaNAs/GaAs and InGaAs/InP singlequantum- well structures have been calculated using microscopic theory including many-body effects and a ... -
Liquid Exfoliated SnP<inf>3</inf> Nanosheets for Very High Areal Capacity Lithium-Ion Batteries
(2021)ncreasing the energy density of lithium‐ion batteries requires the discovery of new electrode materials capable of achieving very high areal capacity. Here, liquid phase exfoliation is used to produce nanosheets of SnP3, ... -
Liquid exfoliation of defect-free graphene
(2013)Due to its unprecedented physical properties, graphene has generated huge interest over the last 7 years. Graphene is generally fabricated in one of two ways: as very high quality sheets produced in limited quantities by ... -
Liquid Exfoliation of Layered Materials
(2013)Not all crystals form atomic bonds in three dimensions. Layered crystals, for instance, are those that form strong chemical bonds in-plane but display weak out-of-plane bonding. This allows them to be exfoliated into ... -
Liquid phase exfoliation and dispersion of two dimensional materials
(Trinity College (Dublin, Ireland). School of Physics, 2014)Over the last few years, it has become clear that due to their high surface area and novel properties, two dimensional materials will be extremely useful both for fundamental studies and for a range of applications. Previous ... -
Liquid Phase Exfoliation of 2D Materials under Ambient Conditions
(Trinity College Dublin. School of Physics. Discipline of Physics, 2021)A technique developed by the Coleman group in 2008 called liquid phase exfoliation (LPE) has been shown to be effective for the delamination of any material exhibiting a layered structure. Molybdenum dioxide ...
