• Diffraction topography — (short: topography ) is an X ray imaging technique based on Bragg diffraction. Diffraction topographic images ( topographs ) record the intensity profile of a beam of X rays (or, sometimes, neutrons) diffracted by a crystal. A topograph thus… …   Wikipedia

• Lattice constant — The Lattice Constant refers to the constant distance between unit cells in a crystal lattice. Lattices in three dimensions generally have three lattice constants, referred to as a , b , and c . However, in the special case of cubic crystal… …   Wikipedia

• diffraction grating — Grating Grat ing, n. [See 2d Grate.] 1. A partition, covering, or frame of parallel or cross bars; a latticework resembling a window grate; as, the grating of a prison or convent. [1913 Webster] 2. (Optics) A system of close equidistant parallel… …   The Collaborative International Dictionary of English

• Reflection high energy electron diffraction — (RHEED) is a technique used to characterize the surface of crystalline materials. RHEED systems gather information only from the surface layer of the sample, which distinguishes RHEED from other materials characterization methods that rely also… …   Wikipedia

• Reciprocal lattice — In physics, the reciprocal lattice of a lattice (usually a Bravais lattice) is the lattice in which the Fourier transform of the spatial function of the original lattice (or direct lattice) is represented. This space is also known as momentum… …   Wikipedia

• Electron diffraction — is a technique used to study matter by firing electrons at a sample and observing the resulting interference pattern. This phenomenon occurs due to the wave particle duality, which states that a particle of matter (in this case the incident… …   Wikipedia

• Bragg diffraction — (also referred to as the Bragg formulation of X ray diffraction) was first proposed by William Lawrence Bragg and William Henry Bragg in 1913 in response to their discovery that crystalline solids produced surprising patterns of reflected X rays… …   Wikipedia

• Dynamical theory of diffraction — The dynamical theory of diffraction describes the interaction of waves with a regular lattice. The wave fields traditionally described are X rays, neutrons or electrons and the regular lattice, atomic crystal structures or nanometer scaled multi… …   Wikipedia
