Scattering from rough surfaces
From Wikipedia, the free encyclopedia
For scattering of light, see Diffuse reflection.
Surface roughness scattering or interface roughness scattering is the elastic scattering of particles against a rough solid surface or imperfect interface between two different materials. This effect has been observed in classical systems, such as microparticle scattering,[1] as well as quantum systems, where it arises electronic devices, such as field effect transistors and quantum cascade lasers.[2]
