The adsorption of ethylene on Si(100)-(2 × 1) has been studied in ultrahigh vacuum. Chemisorption was found to occur via a mobile precursor mechanism. The activation energy difference for desorption and chemisorption from the precursor (Ed − Er),

The background effect in electron stimulated desorption ion angular distribution (ESDIAD) measurements due to soft x‐ray production on Si(111)‐(7×7) is investigated. We find that the background intensity from a Si(111)‐(7×7) surface varies li

The epitaxial growth of an adsorbed layer of NH 3 on top of chemisorbed CO on Ni(111) and Ni(110) surfaces was studied using ESDIAD. A strong interaction yielding an activation energy for NH 3 desorption of ∼12 kcal/mol was observed. This interacti

We report the first observation of ion angular distributions originating from electron stimulated desorption of an adsorbed atomic species on a semiconductor surface (ESDIAD). F+ is emitted from Si(100)-(2×1) along 4 azimuths corresponding to the pr

A study of the surface ionization of gadolinium, terbium, and dysprosium (Gd, Tb, and Dy) is described and the results compared with the predictions of the Saha-Langmuir equation. A tentative measurement of holmium is also included. The experimental

The measurement of the angular distribution of desorbing positive ions produced by electron impact desorption (ESDIAD) is of fundamental importance in understanding molecular structure in the chemisorbed layer. In this short review, two applications
