Transmission Electron Microscopy (TEM)
Transmission Electron Microscopy (TEM) in Serma Technologies offers a wide variety of services and analyses of microstructures down to the atom level.
Typical analyses include structural characterization and elemental composition of various materials such as semiconductors (Si, Ge, GaAs, etc), metals and alloys, carbon composite, quartz, etc…
