Our work at EMSL - Radiation, secondary electrons and surfaces
At EMSL our group is studying the effects of radiation on materials, including water (ice), metal oxides, nitrates, etc.
We are focusing on the damage produced by secondary electrons.
Each primary ion can produce thousands of secondary electrons with energies < 100 eV.
The secondary electron - floats like a butterfly and stings like a bee!
These secondary electrons are active in that they have enough energy to cause excitations in the solid (ionization, dissociative attachment, neutral valence excitations).
Study interactions with electron-stimulated desorption (ESD):
