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 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 of carbonate-intercalated layered double hydroxides
(2019)Direct exfoliation of a carbonate layered double hydroxide (LDH) has been achieved by using a novel horn-probe sonic tip, avoiding the development of time-consuming anion-exchange reactions. The most suitable solvents were ... -
Liquid phase exfoliation of GeS nanosheets in ambient conditions for lithium ion battery applications
(2020)The propensity of many 2D materials to oxidize in ambient conditions can complicate production and limit applications potential. Here we describe ambient liquid phase exfoliation of GeS, a layered material known for its ... -
