Hace 1 día · An EEL spectrum undoubtedly provides a wealth of information, but the goal when using a microscope is to concentrate on images. By 1991, parallel EELS was a well-established technology, thus Gatan focused its R&D efforts on merging spectroscopic and imaging data.
Hace 4 días · Electron energy-loss spectroscopy (EELS) is widely used in analyzing the electronic structure of inorganic materials at high spatial resolution. In this study, we use a monochromator to improve the energy resolution, allowing us to analyze the electronic structure of organic light-emitting diode (OLED) materials with greater precision. This study demonstrates the use of the energy-loss near ...
Hace 5 días · EELS can be combined with microscopy using an electron microscope. This gives energy and/or momentum resolution plus spatial resolution 65. In principle, ...
Hace 4 días · Since local electronic structure in O (oxygen) K-edge in BFO is known to be sensitive to local bonding and geometry 18, an electron energy loss spectrum (EELS) is acquired from the BFO film with...
Hace 2 días · (D, F) Schematic diagram (left panel) of the 1T/2H contact interface made from the above two cases, and cross-section transmission electron microscopy (TEM) image (right panel in D and F) of the resulted hetero-interface in vdWHs. The presence of lithium is confirmed by the electron energy loss spectroscopy (EELS) method (right panel in D).
Hace 3 días · The properties of helium-filled nanopores in amorphous silicon are elucidated by combining theoretical knowledge of helium electronic structure with the results of Scanning Transmission electron microscopy/electron energy loss spectroscopy (STEM/EELS). Two of the properties determined are the density and pressure of the confined helium, these being key properties which are needed for ...
Hace 1 día · Other STEM images, EDS spectra, and EELS spectra, including the ex situ experiments, were collected by a NEOARM (200 kV) including a probe aberration corrector coupled with EELS and EDS detectors, with a 6c probe size and a 40 μm condenser aperture, yielding an approximately 62.5 pA probe current.
