We analyze the momentum-dependent loss function of bulk silver, calculated via the random-phase approximation and based on the band structure from semi-local density functional theory calculations. In the energy range of 0-55 eV the spectrum reveals the ex ...

Encapsulation of Conjugated Oligomers in Single-Walled Carbon Nanotubes: Towards Nanohybrids for Photonic Devices

Cécile Hébert, Barbora Bártová

Visible-light emitting single-walled carbon nanotubes (SWNTs)/organic hybrids have been successfully synthesized and promise to be a photon source to be used in future optoelectronic devices. The nanohybrids are "peapods" having sexithiophene molecules ins ...

Tuning the photophysical properties of soluble single-wall carbon nanotube derivatives by co-functionalization with organic molecules

Cécile Hébert

The photophysical characterization of three soluble derivatives of single-wall carbon nanotubes (SWCNTs), functionalized with poly(ethylene glycol) (PEG), co-functionalized with PEG and aminofluorene and co-functionalized with PEG and aminoanthracene is re ...

Optimal aperture sizes and positions for EMCD experiments

Cécile Hébert

The signal-to-noise ratio (SNR) in energy-loss magnetic chiral dichroism (EMCD)-the equivalent of X-ray magnetic circular dichroism (XMCD) in the electron microscope-is optimized with respect to the detector shape, size and position. We show that an import ...

Magnetic circular dichroism in electron microscopy

Cécile Hébert

Although the analogies between the electron energy loss spectra and X-ray absorption spectra were recognized long ago, the possibility to observe the magnetic circular dichroism in the electron microscope was demonstrated only recently. This technique comb ...

Magnetic circular dichroism in electron energy loss spectrometry

Cécile Hébert

The measurement of circular dichroism in the electron microscope is a new, emerging method and, as such, it is subject to constant refinement and improvement. Different ways can be envisaged to record the signal. We present an overview of the key steps in ...
