Tailoring highly conductive graphene nanoribbons from small polycyclic aromatic hydrocarbons: a computational study
(2013)Pyrene, the smallest two-dimensional mesh of aromatic rings, with various terminal thiol substitutions, has been considered as a potential molecular interconnect. Charge transport through two terminal devices has been ... -
Tailoring magnetoresistance at the atomic level: An ab initio study
(2012)The possibility of manipulating the tunneling magnetoresistance (TMR) of antiferromagnetic nanostructures is predicted in the framework of ab initio calculations. By the example of a junction composed of an antiferromagnetic ... -
Temperature dependence of inverted tunneling magnetoresistance in MGO-based magnetic tunnel junctions
(2010)MgO-based magnetic tunnel junctions (MTJs) of the following main structure: Ir22Mn78 (10 nm) /Co90Fe10 (2 nm) /Ru (0.85 nm) /CoFeB (0.5t<2 nm) /MgO (2.5 nm) /CoFeB (3 nm) have been fabricated, with a thin CoFeB layer in ... -
Temperature dependent coercivity crossover in pseudo-spin-valve magnetic tunnel junctions with perpendicular anisotropy
(2011)We report the temperature dependent collapse of tunnel magnetoresistance (TMR) in perpendicular anisotropy magnetic tunnel junctions (pMTJs) with AlO(x) barriers and (Co/Pt)(3) multilayer electrodes, due to the coercivity ... -
Temperature dependent photoluminescence of nanocrystalline γ-CuCl hybrid films
(2014)Organic–inorganic hybrid films combine the basic properties of organic and inorganic materials and offer special advantages that enhance optical, thermal and mechanical properties. We have studied the temperature dependent ... -
Temperature tuning of two-photon absorption microcavity photodetectors for wavelength selective pulse monitoring
(2008)Temperature tuning of a GaAs two-photon absorption microcavity photodetector with a tuning rate of 0.125 nm per degree is demonstrated. The detector response is shown to be independent of temperature change in the range ... -
Temperature-dependent magnetic second-harmonic generation from Fe nanostructures grown on vicinal W(110)
(2011)Temperature-dependent magnetic second-harmonic generation (MSHG) at normal incidence (NI) is used to determine magnetization curves from Au-capped ultrathin Fe nanostructures grown on a vicinal W(110) substrate. Aligned ... -
Temporal water mobility and sodium intensity measurements in penumbra and core tissue during acute stroke
(2011)The perfusion-diffusion mismatch is a commonly used approach to distinguish between still-viable penumbra and irreversibly damaged core tissue in human stroke patients. However, in recent years it has become clear that the ... -
Tensor-network method to simulate strongly interacting quantum thermal machines
(2020)We present a methodology to simulate the quantum thermodynamics of thermal machines which are built from an interacting working medium in contact with fermionic reservoirs at a fixed temperature and chemical potential. Our ... -
TEXES observations of M supergiants: dynamics and thermodynamics of wind acceleration
(American Astronomical Society, 2009)We have detected [Fe II] 17.94 ?m and 24.52 ?m emission from a sample of M supergiants (? Cep, ? Sco, ? Ori, CE Tau, AD Per, and ? Her) using the Texas Echelon Cross Echelle Spectrograph on NASA's Infrared Telescope Facility. ... -
A theoretical analysis of optical clock extraction using a self pulsating laser diode.
(1999)The potential for using inexpensive compact disc laser diodes as optical clock extraction elements in transparent networks has led to an increase in research into the dynamics of self-pulsating laser diodes. We use a ... -
Theoretical analysis of the performance of a foam fractionation column
(2014)A model system for theory and experiment which is relevant to foam fractionation consists of a column of foam moving through an inverted U-tube between two pools of surfactant solution. The foam drainage equation is used ... -
A theoretical investigation of the influence of gold nanosphere size on the decay and energy transfer rates and efficiencies of quantum emitters
(2016)We present in this contribution a comprehensive investigation of the effect of the size of goldnanospheres on the decay and energy transfer rates of quantum systems placed close to these nanospheres. These phenomena have ... -
Theoretical investigation of the structural, elastic, electronic, and dielectric properties of alkali-metal-based bismuth ternary chalcogenide
(2020)The past decade has witnessed the rapid introduction of organic-inorganic hybrid compounds in photovoltaic applications. Motivated by the strong demand for stable and nontoxic materials in this class, we report a theoretical ... -
Theoretical modelling of physiologically stretched vessel in magnetisable stent assisted magnetic drug targeting application
(2010)The magnetisable stent assisted magnetic targeted drug delivery system in a physiologically stretched vessel is considered theoretically. The changes in the mechanical behaviour of the vessel are analysed under the influence ... -
Theory of cylindrical dense packings of disks
(2014)We have previously explored cylindrical packings of disks and their relation to sphere packings. Here we extend the analytical treatment of disk packings, analyzing the rules for phyllotactic indices of related structures ... -
Theory of diffusivelight scattering from disordered materials
(International Society for Optical Engineering, 1994)It is suggested that the measurement of the angular distribution of light transmitted through a thick slab of diffusively scattering material may provide information about the nature of the local scattering events. Monte ... -
Theory of induced magnetic moments and x-ray magnetic circular dichroism in Co-Pt multilayers
(American Physical Society, 2002)For Co-Pt multilayers, the magnetic moments of the Pt atoms and the x-ray magnetic circular dichroism (XMCD) spectra at the L2 and L3 edge of Pt are calculated-by the ab initio density-functional electron theory. The ...
