Transmission Electron Microscopy Laboratory  

Transmission Electron Microscopy Laboratory




Transmission Electron Microscopy (TEM) is the best technique to view extremely thin and small objects (at the nanometer scale). This is achieved when the sample is shone with a high energy beam of electrons. The basic principles of operation are the same as transmitted light microscope but using electrons instead of light, and this allows for several order of magnitude better resolution, reaching, at the best conditions, features related to individual atoms. In addition, a TEM allows o obtain electron diffraction patterns allowing to access to structural information of the studied samples and to characterized its crystalline nature, or the absence of periodicity.

Main activities of our lab are the nanoscale characterization of materials focusing on: particle size and shape, phases characterization through diffraction and X-ray fluorescence, study of intergrowths and/or exsolutions, studies of defects and interfaces on both natural and synthetic samples.

The laboratory is equipped with

FEI Tecnai F20 Field Emission Gun (FEG) microscope, working at accelerating voltage of 200 kV.

A S-Twin system lens guarantees a point resolution of 0.24 nm, and an energy dispersive X-ray spectrometer (EDS) with ultrathin window allows for chemical characterization at the nanoscale. 

The Transmission Electron Microscopy Laboratory is part of the UNITECH COSPECT - Comprehensive Substances characterization via advanced sPECTtroscopy (https://unitech.unimi.it/)
