Scanning Electron Microscopy

Our SEM is equipped with secondary and backscattered electron imaging.
Cathodoluminescence images can also be produced. Energy-dispersive X-ray detector is available. This can be operated with an ultra-thin window for detection of light elements (2<10).

For any quantitative chemical analyses the electron microprobe should be used.

Transmission Electron Microscopy

When examined by transmission electron microscopy, the silicate mineral kalsilite can be seen to have a lamellar intergrowth texture on a scale of a few hundred Ångstroms.
The TEM is used for sample characterisation, particularly in the study of the formation of microstructures associated with displacive and order/disorder phase transitions.
