Abstract

Surface recoiling and ion scattering from a water and/or oxygen covered Si(001) surface were studied by a Time-of-Flight (TOF) technique for low energy Ne + beam bombardment. The TOF spectra were measured for the sample at various elevated temperatures, from which it is suggested that the technique is useful to study solid surfaces at high temperatures. It was found that the positively charged fraction of recoiled oxygen atoms is dependent on the amount of surface oxygen atoms and increases with it.
