Abstract

The thermal diffuse background between diffracted electron beams has been analyzed with high-energy resolution. The main contribution arises from a surface phonon single-scattering event. The surface phonon dispersion is measured along the $\bar{Γ} - \bar{X}$ direction, and compared with theoretical models.
