Quantification of the information limit of transmission electron microscopes.
نویسندگان
چکیده
The resolving power of high-resolution transmission electron microscopes is characterized by the information limit, which reflects the size of the smallest object detail observable with a particular instrument. We introduce a highly accurate measurement method for the information limit, which is suitable for modern aberration-corrected electron microscopes. An experimental comparison with the traditionally applied Young's fringe method yields severe discrepancies and confirms theoretical considerations according to which the Young's fringe method does not reveal the information limit.

Performance Estimation of a Real-time Aberration Correction System for Scanning Transmission Electron Microscopes
The resolution of a scanning transmission electron microscope remains 100 times worse than its theoretical limit owing to the spherical aberration of objective lens. Ikuta proposed a system to generate an aberration-free amplitude image and phase image using multiple small detectors with real-time signal processing. This study shows the performance optimization results of its signal processing ...
متن کاملStandardless atom counting in scanning transmission electron microscopy.
We demonstrate that high-angle annular dark-field imaging in scanning transmission electron microscopy allows for quantification of the number and location of all atoms in a three-dimensional, crystalline, arbitrarily shaped specimen without the need for a calibration standard. We show that the method also provides for an approach to directly measure the finite effective source size of a scanni...

The scope of the current research is to characterize aging mechanisms in LiFePO4 battery cathodes at the nanometer length scale. For this purpose, we wish to use Electron Energy Loss Spectroscopy (EELS) in the low loss regime in the Transmission Electron Microscope (TEM) to identify and quantify the phases formed in the cathode as the battery is discharged. The above phase identification and qu...

متن کاملReducing Electron Beam Damage with Multipass Transmission Electron Microscopy
With the introduction of hardware aberration correction, direct electron detectors, ultra-bright electron sources and highly precise spectrometers, it seems like we are approaching the pinnacle of transmission electron microscopy (TEM) imaging and spectroscopy. However, the field of electron microscopy is still far from the ultimate signal-to-noise and efficiency limits imposed by electron scat...
