Confined optical modes in small photonic molecules with semiconductor nanocrystals
(2004)
We report on the coherent coupling of whispering gallery modes (WGMs) in a photonic molecule
formed from two melamine-formaldehyde spherical microcavities coated with a thin shell of
light-emitting CdTe nanocrystals ...
Time-resolved X-ray spectroscopy of laser produced plasmas
(American Physical Society, 1980)
X-ray emission spectra, produced by irradiation of neon-filled aluminum-coated glass microballoon and plane aluminum targets, with 100-ps Nd-glass laser pulses, have been time resolved with an x-ray streak camera. The time ...
Multi-walled carbon nanotubes covalently functionalized with polyhedral oligomeric silsesquioxanes for optical limiting
(2010)
A soluble polyhedral oligomeric silsesquioxane (POSS) functionalized multi-walled carbon nanotube (MWCNT) hybrid material (MWCNT/POSS) was synthesized, in which the POSS content was estimated to be 44wt.%. This material ...
Search for alternative magnetic tunnel junctions based on all-Heusler stacks
(2018)
By imposing the constraints of structural compatibility, stability, and a large tunneling magneto-resistance, we have identified the Fe3Al/BiF3/Fe3Al stack as a possible alternative to the well-established FeCoB/MgO/FeCoB ...
The systemic redshift of the quasar 1331 + 170
(American Astronomical Society, 1991)
Infrared spectra covering the 1.6- and 2-micron regions of the quasar 1331 + 170, redshift z = 2.09, were obtained with the CGS4 spectrometer at the UK Infrared Telescope. These spectra show redshifted H-alpha, H-beta, and ...
The evolution and space weather effects of solar coronal holes
(Trinity College (Dublin, Ireland). School of Physics, 2011)
In recent years the role of space weather forecasting has grown tremendously as our society increasingly relies on satellite dependent technologies. As solar activity is the foremost important aspect of space weather, the ...
Exploring the limits of the self consistent Born approximation for inelastic electronic transport
(2009)
The non equilibrium Green function formalism is today the st
andard computational method for
describing elastic transport in molecular devices. This ca
n be extended to include inelastic scattering
by the so called ...
The rate performance of 2D material based battery electrodes may not be as good as is commonly believed
(2020)
Two-dimensional (2D) materials show great potential for use in battery electrodes and are believed to be particularly promising for high-rate applications. However, there does not seem to be much hard evidence for the ...
Cluster expansion constructed over Jacobi-Legendre polynomials for accurate force fields
(2023)
We introduce a compact cluster expansion method constructed over Jacobi and Legendre polynomials to generate highly accurate and flexible machine-learning force fields. The constituent many-body contributions are separated, ...
Nanodomain structure of single crystalline nickel oxide
(2021)
In this work we present a comprehensive study of the domain structure of a nickel oxide single crystal
grown by floating zone melting and suggest a correlation between point defects and the observed
domain structure. The ...
