g, Constant energy contour of the photon energy dependence measurement at the Fermi energy. The size of the electron pocket near \(\varGamma \) does not depend on the photon energy, which confirms its surface-state nature. h, Energy-momentum cut (left) and its second derivative (right) ...
Relative to the 300-kV accelerating field, electrons accelerated under lower voltages are potentially scattered more strongly. Lowering the accelerate voltage has been suggested to enhance the signal-to-noise ratio (SNR) of cryo-electron microscopy (cryo
被引量: 10 摘要: Soft X-rays are very suitable for the examination of biological samples by means of an X-ray microscope. The X-rays are generated by focusing an electron beam onto a fluid jet, thus producing a very small electron focus on the jet and hence a very small monochromatic...
Initial studies of lung micro-mechanics have primarily used a well-established method of sectioning histology combined with a follow-up optical or electron microscopy, which provided a better understanding of the role that the microstructure as well as the whole lung volume plays in the physiology ...
The excitation energy of the OI (1S) is 4.19 eV. Ebihara et al. (2017) calculated volume emission rates at 557.7 nm and 630.0 nm for the precipitation electron flux observed at mid-latitudes during the intense storm on 1989 March 13/14 (with a minimum Dst of −589 nT). According to...
Since the self-interaction correction vanishes for the diffuse orbitals of the uniform gas, all of this exchange energy is due to the Pauli exclusion principle. To characterize the inhomogeneity of the real system, which is missing in the ideal system of the uniform electron gas, we define the...
