Soft-Landing of Complex Ions on Surfaces
EMSL Project ID
19594
Abstract
Interaction of ions with surfaces is an area of active fundamental research in surface science relevant to a broad range of other scientific disciplines supported by the DOE Office of Science such as materials science, mass spectrometry, imaging and spectroscopy. The proposed research will specifically focus on fundamental understanding of reactive and non-reactive deposition of hyperthermal (1-100 eV) peptide, protein and polymer ions on organic surfaces under ultrahigh vacuum conditions. Two major processes are dominant for this range of collision energies: reactive and non-reactive scattering of ions and ion loss on the surface as a result of neutralization or soft-landing of projectile ions. SL and a related process of reactive landing (RL) of ions, in which ion is covalently attached to the surface, are unique processes that occur during collisions of low-energy ions with self-assembled monolayer (SAM) surfaces. Our recent studies on fundamental aspects of SL of peptide ions provide solid support for this work.
