Effects of morphology in electron-stimulated desorption: O − from O 2 condensed on D 2O films grown at 15–150 K on Pt
Electron-stimulated desorption of O − ions from O 2-covered multilayer ice films is investigated as a function of impact energy in the range 6–20 eV. The magnitude of the O − signal is found to strongly depend on temperature (15–150 K) of D 2O condensation on Pt, amount of condensed O 2 (0.1–4 ML) a...

Summary: | Electron-stimulated desorption of O
− ions from O
2-covered multilayer ice films is investigated as a function of impact energy in the range 6–20
eV. The magnitude of the O
− signal is found to strongly depend on temperature (15–150
K) of D
2O condensation on Pt, amount of condensed O
2 (0.1–4
ML) and D
2O film thickness (4–100
ML). The results are shown to be related to different morphologies of the ice layers. |
