EDS(or EDX) is an analytical technique used for the elemental analysis or chemical characterization of a sample. It detects x-rays emitted from the sample during bombardment by an electron beam. Its characterization capabilities are due in large part to the fundamental principle that each element has a unique atomic structure allowing X-rays that are characteristic of an element's atomic structure to be identified from one another. Modern EDS vendors have software/hardware packages that are capable of chemistry identification, elemental mapping and quantitative(phase) mapping. For details of those applications please check out the EDS applications page. Our EDS and EBSD detectors are both purchased from Oxford Instruments.
EBSD is a microstructural-crystallographic technique used to examine the crystallographic orientation of many materials, which can be used to elucidate texture or preferred orientation of any crystalline or polycrystalline material. EBSD can be used to index and identify the seven crystal systems, and as such it is applied to crystal orientation mapping, defect studies, phase identification, grain boundary and morphology studies, regional heterogeneity investigations, material discrimination, microstrain mapping, and using complementary techniques, physico-chemical identification. For details of all those applications, please check out EBSD website.
CL imaging collects cathodoluminescence emitted from the material, which is used to examine internal structures of semiconductors, rocks, ceramics, glass etc. in order to get information on the composition, growth and quality of the material. The CL detector we have is from Gatan. If you are interested in learning more about cathodoluminescence, check out the page of CL theory.
