Momentum-Dependent Charge Transfer Excitations in Sr2CuO 2Cl2 Angle-Resolved Electron Energy Loss Spectroscopy.
Electron-hole pair excitations in the insulating cuprates Sr2CuO2Cl2 were investigated by angle-resolved electron energy loss spectroscopy. The optically allowed and optically forbidden transitions were observed to be strongly anisotropic in Cu − O2 plane. The former show a large energy dispersion ∼ 1.5eV along [110], and the latter appear at a higher energy position (∼ 4.5eV) only along [100],...

متن کاملElectron energy-loss spectroscopy in the TEM
Electron energy-loss spectroscopy (EELS) is an analytical technique that measures the change in kinetic energy of electrons after they have interacted with a specimen. When carried out in a modern transmission electron microscope, EELS is capable of giving structural and chemical information about a solid, with a spatial resolution down to the atomic level in favourable cases. The energy resolu...
متن کاملFundamentals of electron energy-loss spectroscopy
Electron energy-loss spectroscopy (EELS) is an analytical technique that is based on inelastic scattering of fast electrons in a thin specimen. In a transmission electron microscope (TEM) it can provide structural and chemical information about a specimen, even down to atomic resolution. This review provides an overview of the physical basis and new developments and applications of EELS in scan...
متن کاملImage simulation for electron energy loss spectroscopy.
Aberration correction of the probe forming optics of the scanning transmission electron microscope has allowed the probe-forming aperture to be increased in size, resulting in probes of the order of 1 A in diameter. The next generation of correctors promise even smaller probes. Improved spectrometer optics also offers the possibility of larger electron energy loss spectrometry detectors. The lo...
