Jeol 2000FX

Information

The Jeol 2000fx is an analytical transmission electron microscope (TEM). It is relatively straightforward to use and all new TEM users in the RTP begin on this instrument.

It remains the best machine for low magnifications (<20,000x) and also gives great diffraction contrast imaging with a small objective aperture.

Electron diffraction patterns (including high dynamic range patterns) can also be obtained.

Characterisation of graphene oxide

(a) TEM image of a single GO sheet on a lacey carbon support; a double fold is visible in the top right corner. (b) SAED of the centre of the region shown in (a), the diffraction spots are labeled with Miller-Bravais indices. (c) Intensity profile through the diffraction spots labeled in (b). (d) TEM image with two overlapping GO sheets; a SAED pattern from the double sheet region (lower left side) is given in (e). (f) Electron diffraction pattern from a thin film of GO ca. 15 - 20 layers thick.2
