Підтримка: We thank D.L. Allara for supporting us with the substance for the nitrile terminated SAMs, K.L. Kostov, N. Faradzhev and T.E. Madey for helpful discussions, and M. Grunze for support of the SAM related experiments. Help during the experiments by K. Eberle, R. Schneider, and the staff of BESSY, in particular O. Schwarzkopf, H. Pfau, and W. Braun, is gratefully acknowledged. The investigations have been supported by the Deutsche Forschungsgemeinschaft (Fe 347/1-3), by the German BMBF (05 KS4VHA/4 and 05 ES3XBA/5), and by the German Fonds der Chemischen Industrie.

Electronically induced modification of thin layers on surfaces

Анотація:

Interactions of thermally and electronically stimulated reactions in thin layers on surfaces are investigated. For self-assembled monolayers, thermal activation promotes many processes primarily induced by electronic excitations. We demonstrate that the film temperature is an important parameter for steering these reactions towards different final products. Using chemisorbed water on Ru(001) as an example, we investigate how the products of an irradiation induced reaction catalyze thermally stimulated dissociation of water molecules.
