Abstract

Resonance drag losses have been studied by analytical and numerical methods for a neutral beam of 200–400-keV cesium atoms moving near a smooth solid surface bearing IR surface modes. The cases of pure ionic dielectrics, doped semiconductors, and the films of such substances on metal substrates are considered. For the films, the drag losses are approximately twice as large as those for the bulk substances. The theory predicts exponential growth of the drag losses with increasing temperature of the surface.
