明场零损能量筛选

这个貌似是指TEM(隧道电子显微镜)中的一些技术?

zero-loss是指:All inelastically scattered electron are omitted (reduction of noise). That leads to increased contrast in TEM images (important for specimens with low contrast, e.g. biological specimens) or in diffraction patterns.

energy-filtered是指:In the curved magnetic field, electrons with different energies are dispersed. An energy range is selected by a slit located at the dispersion plane. In imaging mode, electrons of the selected energy pass through the lenses of the optical system, and an energy-filtered image occurs at the end of the GIF, where a slow-scan CCD camera is installed for image recording.
