Review: transmission scanning electron microscopy

Journal of Materials Science, 1973
The availability of scanning attachments for transmission microscopes and the advent of very high resolution scanning microscopes now enables materials to be studied in both the back scattered and transmission scanning modes. It is the purpose of this review to present in outline the subject of transmission scanning microscopy, the advocated advantages

Scanning Transmission Electron Microscopy

2018
Scanning transmission electron microscopy (STEM) (Pennycook, Nellist in Scanning Transmission Electron Microscopy, Imaging and Analysis. Springer, New York, 2011 [1]; Tanaka in Scanning Transmission Electron Microscopy of Nanomaterials. Imperial College Press, London, 2015 [2]) is a method of observing a small area using an incident electron probe ...

Scanning transmission electron microscopy of biological macromolecules

Ultramicroscopy, 1980
The practical usefulness of a STEM (Scanning Transmission Electron Microscope) for the study of the structure of biological macromolecules has been investigated using a STEM attachment connected to a TEM (Transmission Electron Microscope), which in one case was equipped with a tungsten hairpin cathode, and in the other case with a field emission gun ...

Scanning moiré fringe imaging by scanning transmission electron microscopy

Ultramicroscopy, 2010
A type of artificial contrast found in annular dark-field imaging is generated by spatial interference between the scanning grating of the electron beam and the specimen atomic lattice. The contrast is analogous to moiré fringes observed in conventional transmission electron microscopy.

Spot-Scan Imaging in Transmission Electron Microscopy

Science, 1991
The determination of the structure of proteins and other organic materials by transmission electron microscopy is a rapidly developing field. Obtaining high-resolution images of these radiation-sensitive specimens has, until recently, been problematic. The development of spot-scan imaging, in which the electron beam is focused to a spot with a diameter

Scanning transmission electron microscopy of thin specimens

Ultramicroscopy, 1976
The intensity distributions in bright field and dark field images of thin specimens obtained in scanning transmission electron microscopy are evaluated in terms of the phase of object approximation for coherent and partially coherent illumination.

Scanning Transmission Electron Microscopy (STEM)

2018
Although Baron Manfred von Ardenne (ZPhys 109:553–572, 1938a, Z Tech Phys 19:407–416, 1938b) developed the first scanning transmission electron microscopy (STEM) in 1938, placing the image lens before the specimen instead of after the specimen as in the Ruska TEM design, it is just a sound idea in principle: he did not use a field emission source such ...

Biological Scanning Transmission Electron Microscopy

1979
Since the demonstration of the visibility of single heavy atoms (CREWE et al., 1971) and unstained biological molecules (CREWE and WALL, 1970) using the scanning transmission electron microscope (STEM), biologists have been excited by the potential of the STEM for biological structure determination.

Scanning transmission electron microscopy of nanostructures

2017
This article investigates nanostructures by means of scanning transmission electron microscopy. The electron microscope is uniquely suited to the study of individual nanostructures, allowing differentiation of different structures and properties that is difficult or impossible to do with techniques that provide a spatial average. The present generation
