摘要：

Impact factor: Electron-impact dissociation reactions in two-adsorbate systems were tuned by applying specific exposure conditions in electron microscopes. Pulsed electron-impact exposure could drive the dissociation reaction of one of the adsorbates into the molecule-limited regime while the reaction of the other adsorbate continued in the electron-limited regime. The pulse period gave control over the composition of the deposit (see scheme). © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
