説明

<jats:p>Auger electron spectrometry has been used to characterize the atomic cesium concentration [Cs]a at the surface of cesium ion bombarded silicon and various metal silicides. The Si− ion yield was found to be proportional to [Cs]v2.8±0.1. Surface cesium concentration was also found to increase with increasing inverse sputtering yield S−1 of the substrate. Deviations from a linear dependence of [Cs]v on S−1 are ascribed to differential sputtering effects.</jats:p>
