Huang scattering

Definition

Huang scattering refers to a specific type of inelastic scattering that occurs when X-rays or neutrons interact with modulated structures, such as complex crystal lattices or materials with periodic variations. This phenomenon provides insights into the dynamics and structural properties of materials by revealing information about their phonon modes, which are crucial for understanding how atoms vibrate within a crystal.
