A photochemical approach for a fast and self-limited covalent modification of surface supported graphene with photoactive dyes.
(2018)
Herein, we report a simple method for a covalent modification of surface supported graphene with photoactive dyes. Graphene was fabricated on cubic-SiC/Si(001) wafers due to their low cost and suitability for mass-production ...
Electronic structure, bonding and dichroism in rutile compounds : an X-ray spectroscopic study
(Trinity College (Dublin, Ireland). School of Physics, 2012)
Rutile-type transition-metal compounds are a continually rewarding area of research,
of both technological and fundamental importance due to their exhibiting
a wide variety of physical properties, lending to numerous ...
Symmetry-dependent electron-electron interaction in coherent tunnel junctions resolved by measurements of zero-bias anomaly
(2014)
We provide conclusive experimental evidence that zero-bias anomaly in the differential resistance of magnetic tunnel junctions is due to electron-electron interaction (EEI), clarifying a longstanding issue. The magnon ...
Fundamental gap of molecular crystals via constrained density functional theory
(2016)
The energy gap of a molecular crystal is one of the most important properties since it determines the crystal
charge transport when the material is utilized in electronic devices. This is, however, a quantity difficult ...
Performance and preliminary calibration of the Hopkins ultraviolet telescope on the Astro-2 mission
(American Astronomical Society, 1995)
An improved version of the Hopkins Ultraviolet Telescope (HUT) made its second flight on the Astro-2 mission aboard the Space Shuttle Endeavour from 1995 March 2--18. The longer mission duration and greatly improved pointing ...
Quantum condensation from a tailored exciton population in a microcavity
(2009)
An experiment is proposed on the coherent quantum dynamics of a semiconductor microcavity containing
quantum dots. Modeling the experiment using a generalized Dicke model, we show that a tailored excitation
pulse can ...
Giant spontaneous Hall effect in zero-moment Mn2Ru x Ga
(2015)
Spin-dependent transport properties of Mn2Ru x Ga thin-films are studied as function of the Ru concentration and the substrate-induced strain. The large spontaneous Hall angle of 7.7% twenty times bigger than in other 3d ...
Free Exciton Spectra in Heteroepitaxial ZnSe/GaAs layers
(American Physical Society, 2000)
The free-exciton photoluminescence (PL) and reflection spectra of metal-organic vapor-phase-epitaxy grown ZnSe/GaAs epilayers with a thickness greater than that of the strain relaxation thickness were studied experimentally ...
EG and: Far ultraviolet spectroscopic explorer and Hubble space telescope STIS monitoring of an eclipsing symbiotic binary
(American Astronomical Society, 2008)
We present highlights and an overview of 20 FUSE and HST STIS observations of the bright symbiotic binary EG
And. The main motivation behind this work is to obtain spatially resolved information on an evolved giant star ...
Improved adhesive strength and toughness of polyvinyl acetate glue on addition of small quantities of graphene
(2013)
We have prepared composites of polyvinyl acetate (PVAc) reinforced with solution exfoliated graphene. We observe a 50% increase in stiffness and a 100% increase in tensile strength on addition of 0.1vol% graphene compared ...
