The adsorption of cyanogen iodide (ICN) on a silicon (100) surface is studied by X-ray photoelectron spectroscopy (XPS). At room temperature, ICN chemically adsorbs on the surface. The C 1s photoelectron peak indicates that the carbon nitrogen triple bond is intact. The triple bond remains until approximately 400C. Initial experiments suggest a sticking coefficient at room temperature of 0.1 for ICN. Experiments are in progress to quantitatively determine this number. In addition, thermal desorption measurements are proceeding to further complementing the XPS studies.
