Electron- and photon-stimulated desorption
Electron and Photon Stimulated Desorption (ESD and PSD) have recently received growing attention because of their ability to provide highly specific information on the surface bond. In one sense, stimulated desorption can serve as an electronic and structural probe specific to the desorbed species and its surface bonding environment. This arises from our knowledge of the excitation processes which initiate desorption, and the intrinsic electronic properties of the surface which govern desorption processes. Alternatively the desorption experiment can provide insight into the dynamics of charge motion in the surface bond. The desorption process is a complex interplay between electronic and nuclear motions which occur in response to the highly energetic and localized electronic excitations which are known to induce desorption. The mechanisms of desorption, desorption modeling in covalent systems, and desorption spectroscopy are discussed. 71 references. (WHK)
