The Transmission Electron Microscope
1998This chapter gives a short description of the physical instrumentation of the transmission electron microscope (fixed beam and scanning modes). It starts with the fundamental physics of electron dynamics for energies in the range 100–1000 keV. Some types of magnetic lenses and aberration correctors used to focus the electrons in the microscope are ...

Microanalysis in the transmission electron microscope
Micron (1969), 1980Abstract The major subject of the review is the determination of the chemical composition of a thin specimen by analysis of the X-rays generated within it in the transmission electron microscope. Most emphasis is placed on the use of energy dispersive X-ray detectors attached to modern CTEM/STEM instruments.

The Transmission Electron Microscope
2005As we saw in Chapter 1, the TEM is capable of displaying magnified images of a thin specimen, typically with a magnification in the range 103 to 106. In addition, the instrument can be used to produce electron-diffraction patterns, useful for analyzing the properties of a crystalline specimen.

Aberrations in the Transmission Electron Microscope
Proceedings, annual meeting, Electron Microscopy Society of America, 1970Three aberrations contribute to the loss of image resolution in the transmission electron microscope; spherical (SA=Csα3), chromatic (CA=Ccα△VV-1) and diffraction (DA=O.61ƛα-1). For high voltage incident electrons and thin materials most microscopists assume resolution is controlled by spherical and diffraction aberrations.

The Scanning Transmission Electron Microscope
2008The scanning transmission electron microscope (STEM) was a rediscovery or reinvention whose conception was based on techniques and processes in nuclear physics, and it was lamentably ignorant of any precedent. This chapter is concerns the principles of operation of the STEM, paying particular attention to the limits of performance, it is helpful first ...

TRANSMISSION ELECTRON MICROSCOPE (TEM)
2021Transmission Electron Microscopy (TEM) is used for the simultaneous determination of micro/nano and crystal structure of inorganic and organic materials. Devices with lanthanum hexaboride (LaB6) electron gun operating under accelerating voltage in the range of 40-200 kV are particularly suitable for imaging biological, polymeric and nano-structured ...

Elements of a Transmission Electron Microscope
1984Not only does the gun of an electron microscope emit electrons into the vacuum and accelerate them between cathode and anode, but it is also required to produce an electron beam of high brightness and high temporal and spatial coherence. The conventional thermionic emission from a tungsten wire is limited in temporal coherence by an energy spread of ...
