JEOL JEM 2800 Scanning Transmission Electron Microscope

The JEM 2800 is capable of providing sub nanometer resolution images. It has both secondary and transmission electron imaging modes that allow for visualization of the bulk as well as the surface of the material under analysis. Fast elemental mapping and composition analysis is made possible by the unique dual SDD design.

When publishing work with data collected from the JEOL 2800, the following should be used for acknowledgment:

“This work made use of University of Utah USTAR shared facilities supported, in part, by the MRSEC Program of NSF under Award No. DMR-1121252.”
