Transmission Electron Microscope
Operated by
Brookhaven's Materials Science Department, the 300,000 electron-volt high-resolution Transmission Electron Microscope
(TEM) was manufactured under Brookhaven's direction by the Japanese
Electro-Optical Laboratory of Tokyo. A structure characterization facility that
can be used on various materials, TEM produces information that complements both
neutron and synchrotron x-ray studies.
The best of its kind in the U.S., TEM can magnify a sample up to 50 million
times its size, with a spatial resolution of 0.1 nanometer (nm). It also has
many state-of-the-art attachments that provide powerful tools for researchers to
study crystal structure, electronic structure, and chemical composition of
materials. TEM has an energy filter, an x-ray energy dispersive spectrometer, an
electron energy-loss spectrometer, and several digital data recording systems.
TEM is also equipped with a holography unit, a scanning attachment with chemical
mapping resolution better than 1 nm, and cooling and heating in-situ stages that
can heat or cool specimens to temperatures ranging from 15-1300 kelvins (-258 to
+1027 degrees Celsius).
Another unique capability of this TEM is its minimum probe size -down to
approximately 0.3 nm. This is extremely useful for nano-technology research,
which can reveal remarkable amounts of structural information from a
sub-nanometer volume.
