This study focuses on elucidating the bond breaking steps involved in the electron beam induced deposition (EBID) of nanostructures created from the organometallic precursor cobalt tricarbonyl nitrosyl (Co(CO)3NO) by studying the effect of 500 eV incident electrons on nanometer scale films of Co(CO)3NO. Experiments were performed under ultrahigh vacuum conditions, using a suite of surface analy...

Preliminary studies performed with the cold bore superconducting undulator installed in the ANKA (Angstrom source Karlsruhe) storage ring suggest that the beam heat load is mainly due to the electron wall bombardment. Electron bombardment can both heat the cold vacuum chamber and induce an increase in the pressure because of gas desorption. In this contribution we compare the measurements of th...

Electron-stimulated desorption of F and Cl from submonolayer CF2Cl2-covered Ru(0001) is strongly affected by coadsorption of polar molecules (H2O and NH3) and nonpolar rare-gas atoms (Xe, Kr, and Ar). Giant anionic enhancements (up to 102-104) are observed for polar molecules, which are several orders of magnitude higher than by nonpolar atoms. The giant enhancements are attributed to enhanced ...

The electron stimulated desorption of D anions from deuterated hydrocarbons condensed on a platinum substrate has been studied experimentally. D anion yield functions are reported for incident electron energies ranging from 0 to 20 eV: For each molecule studied, the yield function exhibits a single dissociative attachment resonance at approximately 10 eV: Above 15 eV; a linearly increasing D io...
