Abstract

Water bilayers deposited on Ru(0001) have become a benchmark system for water interacting with solid surfaces. Here, we report diffraction data recorded using He-atom scattering demonstrating the presence of an only weakly disturbed bilayer of D2O on Ru.

Results obtained method cannot be affected by e-beam so far made experimental determination important model difficult. We find high-order commensurate, stable water bilayer exhibiting a structure which is not compatible with any of the previously published structural models this system. The cross section for e-induced damage has also been determined.
