Recent Colloquium

As we know, microscopy played a key role in the development of advanced technologies and new materials for the progress of mankind. In the present talk, a brief description of the essential features of the theory of field emission, field ionization and field desorption would be given. The importance of field electron / ion microscopy (FEM/FIM) and atom probe field ion microscopy (APFIM) would be highlighted in gaining a deeper understanding of materials at atomic scale.
