AbstractWe study electromagnetic response functions for metallic surfaces with diffusive carrier transport. The electric field noise at a distance z0 from the surface is evaluated and compared with data from ion chips that show anomalous heating with a noise power decaying as z0-4. We find that a layer of surface charge with strong diffusion can account for the latter result. file generated: 25 Apr 2011
