Observation of a novel electron beam effect: electron-stimulated associative desorption
We observed diatomic hydrogen and nitrogen desorbing from Pt(111) surfaces covered with multilayer ammonia at 120 K during electron irradiation at 600 eV. Experiments were conducted to verify that the source of H 2(g) and N 2(g) species was indeed the electron-irradiated ammonia multilayer. This eff...

Summary: | We observed diatomic hydrogen and nitrogen desorbing from Pt(111) surfaces covered with multilayer ammonia at 120 K during electron irradiation at 600 eV. Experiments were conducted to verify that the source of H
2(g) and N
2(g) species was indeed the electron-irradiated ammonia multilayer. This effect, which we describe as electron-stimulated associative desorption (ESAD), has not been previously reported. |
