Atomic-resolution Imaging Using Cs-corrected Vortex Beams
Phase gratings have been shown to produce electron beams with orbital angular momentum as demonstrated by numerous groups, and show promise for electron magnetic circular dichroism (EMCD) at the atomic scale [1, 2]. A linear diffraction grating will produce diffracted beams with a separation determined by the pitch or spacing between grating lines. A grating with a central line that forks into ...
متن کاملCoalescence and sintering of Pt nanoparticles: in situ observation by aberration-corrected HAADF STEM.
An aberration-corrected JEOL 2200FS scanning-transmission electron microscope (STEM), equipped with a high-angle annular dark-field detector (HAADF), is used to monitor the coalescence and sintering of Pt nanoparticles with an average diameter of 2.8 nm. This in situ STEM capability is combined with an analysis methodology that together allows direct measurements of mass transport phenomena tha...
متن کاملMonochromator for Aberration-Corrected STEM
In a scanning transmission electron microscope (STEM), the elemental analysis at atomic resolution is realized by the combination with electron energy-loss spectroscopy (EELS), since an aberration corrected probe forming lens system enables us to obtain an electron probe sized about 0.1 nm [1]. In EELS, the energy resolution is mainly limited by the energy spread of the electron source, which i...
متن کاملObservation of Radial Ring Deformations using Closed Orbits at LEP
With a circumference of 26.7 km the LEP ring is subject to long range geological deformations which must be monitored accurately to guarantee a sufficient precision on the beam energy for the LEP experiments. Changes of the LEP circumference can be extracted from the radial position of the closed orbits with an accuracy better than 0.1 mm. The observed tidal deformations with amplitudes of up t...
متن کاملInvestigation of 6T@SWNTs by Cs corrected TEM
Conjugated rigid rod molecules are extensively studied for their optical and semiconducting properties. Since their size is suitable for the inclusion in SWNTs, they are optimal candidates molecules to obtain hybrid systems emitting in the visible spectral range [1]. Such hybrids systems are called peapods where the nanotube is the “pod” and the inserted molecule the “pea”. Successful encapsula...
