Probing dynamics at surfaces with X-rays and neutrons

Abstract

We discuss some of the interesting problems associated with dynamical phenomena at surfaces and in thin films and methods to probe such dynamics, using neutron or X-ray scattering and related spectroscopic methods.

Keywords:

• Surfaces
• Interfaces
• Inelastic scattering
• Correlation spectroscopy
• Capillary waves
• Spin dynamics
