Definition of "Diffusion" |
The scattering of reflected light waves from an object, such as white paper. Controlled application of impurity atoms to a semiconductor substrate. / Diffusion, in acoustics and architectural engineering, is the efficacy by which sound energy is spread evenly in a given environment. A perfectly diffusive sound space is one that has certain key acoustic properties which are the same anywhere in the space. A non-diffuse sound space would have considerably different reverberation time as the listener moved around the room. Virtually all spaces are non-diffuse. / (1) a region of a semiconductor into which a very high concentration of impurity has been diffused in order to substantially increase the majority carrier concentration in that region. |
